MLCC Enters Its Own Supercycle: Another Round of Increases Lands Late October, Lead Times Stretch to 40 Weeks

Memory is not the only passive bottleneck any more. MLCCs — the ceramic capacitors that sit by the dozen on every board — have entered a supply cycle of their own, and the next price step is already dated. Yageo is circulating plans for a new round of increases in late October through November 2026, covering the rest of this year and into 2027 Q1: high-capacitance part numbers up 50% or more, general-specification parts up 10–30%. The pattern is familiar to anyone who watched DRAM this year, and it is landing in the same procurement window.

What has already moved

• Murata raised prices on AI-server and automotive-grade MLCCs by 15–35% in April 2026, and has continued to prioritise high-end lines. High-end line utilisation is reported at 90–95%.
• Samsung Electro-Mechanics raised all product prices by 30% effective 1 August 2026, and is reported to have been first to lift Q4 2026 quotes to OEM and ODM customers.
• Taiyo Yuden issued a price-adjustment notice on 23 July, effective 1 September, after already completing two rounds on automotive and high-capacitance lines.
• Yageo raised prices 50% in July and, having held since, is now preparing the next step for late October.
• Domestic Chinese makers are following: Sanhuan raised distributor prices 10–30% in October.

The supply numbers are tighter than the price headlines suggest. Order-to-shipment ratios at the end of June 2026 reached 1.30 at Murata, 1.31 at Samsung Electro-Mechanics and 1.25 at Taiyo Yuden — all records since the pandemic. Murata reported backlog of JPY 617.7bn at the end of its June quarter, up 38.5% on the prior quarter, with MLCC capacitor backlog up 49.4% and new MLCC orders up 85.5% year on year. Global distributor inventory hit a record low in early August, and unit-price indices have since moved higher again.

The lead-time shock is the real story

Prices are visible; lead times are what break production schedules. High-value-added MLCCs have moved from a normal 8–10 weeks to 20–26 weeks. High-capacitance parts — the ones that carry the most capacitance in the smallest case sizes — have gone from 8–12 weeks to 26–40 weeks. Some Samsung Electro-Mechanics lines are reported at roughly 40 weeks. Spot prices on the most constrained high-capacitance specifications rose 60–80% through August.

The demand is not consumer. It is the non-GPU accelerator build-out: Google TPU and AWS ASIC programmes, whose orders have flowed through to EMS and power-supply makers, with concentrated pull-in from Q4 2026 and volume ramp expected in 2027. That demand hits exactly the specifications that are hardest to substitute — high capacitance, high voltage and large case sizes such as 1206 and 1210 — while Murata has issued a discontinuation notice covering some consumer-grade GRM and GRJ part numbers, with a final shipment date of 31 March 2029.

What a buyer should do now

• Stop optimising on unit price alone. A part you cannot get is more expensive than a part that costs 30% more. Score BOM lines on availability and lead time, not just cost.
• Treat the small passives as a risk, not a rounding error. A board may carry a hundred MLCCs worth fractions of a cent each — and one constrained high-capacitance value can stop the line. Run an availability check across the whole capacitor BOM, not just the expensive silicon.
• Lock what you can, when you can. The next increase is being negotiated alongside 2027 Q1 quarterly pricing and annual agreements. If you have volume visibility, get it into a long-term agreement now rather than buying spot later.
• Plan substitutions before you need them. General-specification and mid-capacitance values have more replacement headroom than the high-capacitance, high-voltage lines. Have a qualified second source in place while there is still time to test it.
• Start last-time-buy planning on affected part numbers. Where a maker has announced a discontinuation with a 2029 final-shipment date, the buying decision happens well before the date itself — and prices on the tail are rarely friendly.
• Shorten your quote validity. With component pricing moving monthly, a quotation that assumed last quarter's capacitor cost is already stale.

Our position

We build our repellers and our PCBA work from the same component market you buy in, so we are not insulated from this cycle — and we will not pretend a quotation is fixed when the underlying passives are re-pricing monthly. What we do is mark the short-lead-time and single-source lines on the BOMs we quote, tell you which values are exposed, and suggest alternates where a qualified substitute exists. If you are working through a board with a constrained MLCC, send us the BOM and we will flag where the supply risk sits. Our earlier note on the memory supercycle covers the same dynamic on the storage side, and our PCB and PCBA capability list is here.
