Your September MLCC quotes do not agree with each other: the standard 0402 and 0603 parts came back slightly cheaper than in August, while the high-capacitance parts on the server board came back more expensive, with longer lead times. Both quotes are correct, and that is the whole story of the MLCC market in September 2026.
September 2026 in One Minute: A Two-Speed MLCC Market, Not a Price Crash
The short answer is that multilayer ceramic capacitors moved in two opposite directions last month. According to TrendForce's MLCC price assessment published on 30 September 2026, channel prices for low- to mid-capacitance standard consumer MLCCs weakened, while high-capacitance and advanced-specification products for AI servers stayed firm because supply remained tight, a dynamic similar to what is already playing out in memory components NAND Flash Shortage 2026: Why Supply Stays Tight Until 2028.
The quarterly picture confirms the split rather than contradicting it. The Asia Passive Components Price Tracker for Q3 2026, published by Epignosis Insights on 5 October 2026, puts the standard MLCC index at 132 against a Q3 2025 base of 100, up 10.0% quarter on quarter and 32.0% year on year. The high-capacitance and AI-grade index stands at 205, up 24.2% quarter on quarter and 105.0% year on year. Those figures cover July through September as a whole, so they should be read as quarterly indicators, not as September-only prices. Even so, they show that the September softening in standard parts happened inside a year in which both categories ended well above their 2025 level.
Who is affected: any OEM or EMS provider whose bill of materials mixes consumer-grade decoupling capacitors with high-capacitance parts for power delivery on server, networking or industrial compute boards. Those two lines in the BOM no longer share a price trajectory.
The practical consequence for procurement is simple. A single blended "MLCC price" assumption in a Q4 budget is wrong this quarter, in one direction or the other, depending on the mix.
What Pushed Standard Consumer MLCC Prices Down in September 2026
Standard consumer MLCC prices softened because end demand disappointed, not because manufacturers cut their list prices. TrendForce's September 2026 report attributes the weakness to an underwhelming back-to-school season and weak component pull-ins from consumer-electronics ODMs, with channel prices for low- to mid-capacitance products falling during the month.
The point worth underlining is where the movement occurred. TrendForce describes channel prices falling during the month. That is a distributor and spot signal, driven by stock positions, and it can reverse as quickly as it appeared once ODM order books refill.
Context matters, because September's dip sits on top of a steep increase earlier in the year. According to TrendForce, Samsung Electro-Mechanics applied a 30% shipment-price increase effective 1 August 2026, Walsin Technology raised consumer-MLCC prices by 5% to 15%, and Taiyo Yuden's interim April increase on consumer-grade MLCCs ranged from 6% to 13%. The Epignosis Insights tracker's standard index of 132 for Q3 2026 (+32.0% year on year) tells the same story from the demand side.
Read this way, September is a correction within an elevated price base. Buyers of standard-grade MLCCs may see short-term relief on channel pricing in October, and it is reasonable to take advantage of it for near-term requirements. It is not reasonable to rebase a 2027 cost model on it.
Why High-Capacitance and AI-Server MLCCs Didn't Follow the Same Trend
High-capacitance and advanced-specification MLCCs stayed firm for one reason: supply did not loosen. TrendForce's September 2026 assessment reports that AI-server demand continued to absorb available capacity, so the consumer-side slack never reached this segment, echoing how AI-driven demand has kept another critical component category allocated for years rather than quarters NAND Flash Shortage 2026: Why Supply Stays Tight Until 2028.
The scale of that demand explains why. According to TrendForce, a single AI server cabinet can consume up to 440,000 high-end MLCCs. One rack of GPU servers therefore represents a capacitor volume comparable to a sizeable consumer-electronics production run, concentrated on a narrow set of high-capacitance, low-ESL part numbers that only a few lines in the world produce at volume.
On top of demand, input costs rose. TrendForce reports that Taiyo Yuden's new MLCC shipment prices took effect on 1 September 2026, with the manufacturer citing sharp cost increases in barium-titanate powder, nickel powder and rare-earth additives . The same source reported Taiyo Yuden's April interim increase of 10% to 30% on high-capacitance automotive-grade parts. Material inflation and allocation are therefore stacking on the same part numbers.
The spot market shows what that stacking produces. TrendForce observed distributors raising quotations and spot prices for selected supply-constrained models reaching two to three times earlier levels . That multiple applies to specific short-supply models, not to the category as a whole, but it is exactly the figure a buyer meets when a line-down situation forces an open-market purchase.
The Epignosis Insights Q3 2026 index of 205 for high-capacitance and AI-grade parts, up 105.0% year on year , should be treated as the baseline for planning. For programs with server or AI content, the sources describe a category where supply remained constrained through September 2026; how long that tightness lasts is not established in the available data, so planning should assume continued allocation risk rather than a quick return to normal, a planning posture that mirrors the multi-year supply outlook procurement teams are already building into memory roadmaps NAND Flash Shortage 2026: Why Supply Stays Tight Until 2028.
Murata's Three-Year Exit From Standard MLCCs: What Changes for Buyers
Murata is stepping back from low-margin conventional MLCCs, and that changes the sourcing map for legacy BOMs more than any single month of pricing. TrendForce's September 2026 report states that Murata is phasing out low-margin conventional MLCC products, with Taiwanese and Chinese manufacturers expected to gradually capture standard orders over a three-year transition period.
Three years sounds comfortable. For an industrial or medical product with a ten-year lifecycle, it is not. Part numbers currently sourced from Murata's standard line can receive product-change or discontinuation notices at any point inside that window, and allocation on those part numbers will tighten before the formal end-of-life date, because the manufacturer has no incentive to add capacity on a line it is winding down. The mismatch between BOM lifecycle and supplier roadmap is the real risk here.
The second consequence is that qualification becomes a multi-year program rather than a one-off substitution. Standard MLCCs look interchangeable on a datasheet, but a 0603 X7R 100 nF from a different manufacturer can differ in DC bias behaviour, piezoelectric noise and termination material, which matters for automotive, aerospace and medical qualification files.
The third consequence is documentation. Moving standard-MLCC volume toward new manufacturers raises questions about certificate-of-conformance continuity, change-notification processes and second-source validation that need to be answered before the first order, not after the first failure in the field. Price is the easy part of this transition.
What September's MLCC Price Split Means for OEM and CEM Procurement Decisions
Split the budget by category first, then decide where to buy. For mixed BOMs, the 14-point gap between the standard index (+10.0% quarter on quarter) and the high-capacitance index (+24.2% quarter on quarter) in the Epignosis Insights Q3 2026 tracker is too wide for a blended assumption to survive a cost review.
For programs dependent on high-capacitance or AI-grade MLCCs, the supply constraints reported by TrendForce for September 2026 mean continued allocation risk should be assumed in near-term planning, without a defined end date in the available data, the same kind of extended-horizon risk procurement teams are already pricing into AI-driven memory budgets NAND Flash Shortage 2026: Why Supply Stays Tight Until 2028. Tight capacity plus input-cost pressure on nickel powder and rare-earth additives means lead times and price volatility are likely to persist, and the correct posture is to lock volume on the critical part numbers now, where authorised channels can commit, and to pre-identify qualified alternative sources for the remainder.
For programs still specifying Murata standard-line MLCCs, the decision is also clear. Start the second-source qualification immediately on the part numbers with the longest remaining product life, because the three-year transition reported by TrendForce is a ceiling, not a guarantee, and because the September softening in standard pricing makes this the cheaper moment to buy qualification samples and build a bridge stock.
For programs buying standard parts only, take the September relief on near-term requirements but keep the Q3 2026 index level of 132 as the planning baseline. Buying twelve months of stock on a dip is rarely justified for passives with short shelf-life constraints on solderability.
When a purchasing team hesitates between waiting for prices to fall further and securing supply, the answer depends on the category. On standard consumer parts, waiting a few weeks is a defensible bet. On high-capacitance AI-grade parts, waiting is the expensive option.
How a Specialised Sourcing Broker Handles an MLCC Allocation Gap: A Worked Scenario
Here is how an allocation gap on high-capacitance MLCCs typically plays out for an EMS provider in the current market, and what a shortage-focused broker such as Origin Sourcing actually does with it.
The situation. A European EMS building an AI-accelerator carrier board receives a notice from its franchised distributor in late September: the 22 µF 0805 X6S part on the power-delivery network is on allocation, the next committed delivery slips eight weeks, and the shortfall is 180,000 pieces against a build scheduled in five weeks. The line stops in roughly ten working days without those parts.
Step one is to define the real constraint. The broker's first call with the purchasing director establishes three things: the latest acceptable dock date, the authorised alternates already on the approved vendor list, and whether the customer's quality file accepts parts from a non-franchised source with full traceability. That last point decides which stocks are even worth looking at.
Step two is physical stock identification, not catalogue scraping. Over 48 to 72 hours, the search runs through excess inventory held by other EMS providers and OEMs, distributor stock in Asia and North America, and manufacturer-authorised surplus channels. In the current market, TrendForce's observation of spot prices at two to three times earlier levels on supply-constrained models means several offers will come from sources with no documentation at all. Those are discarded, however attractive the lead time.
Step three is source qualification. For each candidate lot, the broker requests the original manufacturer's certificate of conformance, lot and date-code information, packaging photos, and the chain of custody from the manufacturer to the current holder. For MLCCs specifically, moisture-sensitivity handling and reel integrity are checked, because a resealed reel of high-capacitance parts stored badly for two years is a field-failure risk, not a saving. Incoming inspection, including sample electrical testing against the datasheet, is arranged before release to the line.
Step four is the arbitration. The purchasing director is presented with two options: 180,000 pieces from a single traceable excess lot held by an OEM in Taiwan, deliverable in nine days at a premium, or 110,000 pieces from the same lot plus a bridge of 70,000 pieces of a pre-qualified alternate manufacturer's part on the approved vendor list, deliverable in twelve days at a lower blended cost but requiring a documented BOM deviation. The broker recommends the second option when the deviation process can close in time, and the first when it cannot. That recommendation is made by the person who will be accountable if the line stops, with direct involvement of the broker's management rather than a ticket in a queue.
The lesson from the scenario is not that brokers exist. It is that in a two-speed market, the sourcing method has to match the category: standard parts can wait for the channel to settle, while high-capacitance parts need physical stock located, documented and inspected before the schedule slips.
FAQ
Did MLCC prices fall in September 2026?
Only in one segment. TrendForce's assessment published on 30 September 2026 reports that channel prices for low- to mid-capacitance standard consumer MLCCs declined, while high-capacitance and AI-server-grade MLCCs remained firm because supply stayed constrained. There is no single market-wide price decline in the available data.
How much did AI-grade MLCC prices rise compared to standard parts?
According to the Epignosis Insights Q3 2026 tracker, the high-capacitance and AI-grade MLCC index reached 205 (up 24.2% quarter on quarter and 105.0% year on year, with Q3 2025 as the base of 100), while the standard MLCC index reached 132 (up 10.0% quarter on quarter and 32.0% year on year). These are quarterly figures covering July to September, not September-only prices.
Why are high-capacitance MLCCs in short supply?
TrendForce reports that a single AI server cabinet can consume up to 440,000 high-end MLCCs, concentrating demand on a narrow set of part numbers, the same AI-infrastructure pull that is also driving sustained tightness in memory supply NAND Flash Shortage 2026: Why Supply Stays Tight Until 2028. At the same time, Taiyo Yuden's shipment prices effective 1 September 2026 cited sharp increases in barium-titanate powder, nickel powder and rare-earth additive costs, so material inflation and allocation are affecting the same products.
What should buyers do about Murata phasing out standard MLCCs?
Start second-source qualification now on the part numbers with the longest remaining product life. TrendForce reports a three-year transition during which Taiwanese and Chinese manufacturers are expected to absorb standard orders, but discontinuation notices and allocation shifts can arrive well before that window closes, and updating qualification files for regulated products is a lengthy process whose duration depends on the product, the regulatory framework and the customer's change-control procedure.
Is it safe to buy MLCCs on the open market during an allocation?
It is manageable when the source is qualified before purchase: manufacturer certificate of conformance, lot and date-code traceability, verified chain of custody, and incoming inspection with sample electrical testing. Offers without documentation should be rejected regardless of lead time, particularly on high-capacitance parts where spot prices on constrained models have reached two to three times earlier levels, according to TrendForce.
