The notice went out to distributors this week, and its terms were unusually blunt. Samsung Electro-Mechanics, the world’s second-largest maker of multilayer ceramic capacitors, told customers that from August 1, prices across its entire MLCC product line will rise 30%, and that supply chain pressure had exceeded the company’s tolerance limit. The notice added a sentence that procurement managers rarely hear from a supplier: even if customers accept the new prices, there is no guarantee of timely delivery.
The components in question are the most basic in electronics. MLCCs store and release small amounts of electrical charge, stabilizing voltage and filtering noise in nearly every circuit, and a single smartphone uses more than a thousand of them. They are cheap, they are everywhere, and for most of the past decade their price moved in one direction: down. The industry has been underpricing capacity for years, and the AI buildout has turned the quietest corner of the supply chain into one of its tightest.
The demand story is the same one driving the rest of the semiconductor industry, with a twist. AI servers use vastly more capacitors than conventional servers, because high-power accelerators create sudden swings in current draw that require large numbers of small, high-capacitance, heat-resistant MLCCs around the power delivery circuits. TrendForce estimates a single AI server cabinet consumes up to 440,000 high-end MLCCs. At the same time, the manufacturing base is limited: capacitor production lines are expensive, qualification cycles are long, and the suppliers that dominate the market, Murata, Samsung Electro-Mechanics, Taiyo Yuden, Yageo, have been conservative about adding capacity.
The no-delivery-guarantee clause matters because it changes buyer behavior. In a normal market, a price increase is met with negotiation and substitution; in a shortage, it is met with hoarding. Procurement teams are already placing orders far beyond their needs to secure allocation, which deepens the apparent shortage and invites another round of increases. The industry has seen this dynamic before: the 2017-2018 MLCC shortage, driven by a surge in smartphone and automotive demand, produced multi-year price spikes, allocation quotas and a wave of counterfeits that took distributors years to clean up.
The price increases are cascading across the industry. Murata, the largest supplier, raised prices on AI and automotive-grade products twice this year, with increases of 15% to 40%. Taiyo Yuden is preparing a September increase, citing the cost of barium titanate powder, nickel and rare earth additives. Yageo raised prices across its capacitor, resistor and inductor lines in July, and Kemet, the Taiwanese passive component maker, has pushed some models up 50% to 80%. Samsung Electro-Mechanics’ across-the-board 30% move is the biggest single announcement so far, and it signals that the suppliers no longer believe the tightness is temporary.
The financials explain the confidence. Samsung Electro-Mechanics posted second-quarter revenue of 3.457 trillion won, up 24.2% from a year earlier, and operating profit of 440.4 billion won, more than double the prior year. Its component business, the MLCC unit, grew 29%, driven by AI data center servers and automotive applications. The company has signed long-term agreements with more than 10 AI server customers, including major hyperscalers and chip designers, and in July alone disclosed two AI server MLCC contracts worth roughly 745 billion won with deliveries locked through 2027. Its book-to-bill ratio hit 1.31 in June, meaning orders outpaced shipments by nearly a third, and inventory of some general-purpose products has fallen below 30 days.
The price increases will travel through the supply chain before they reach consumers. Contract manufacturers and handset makers buy capacitors months ahead of production, and the August increase will hit components sourced for the holiday build. Apple and Samsung, whose next-generation flagship phones are assembled in the second half of the year, will feel it first, and electronics makers across the board are accelerating purchases to lock in current prices before the next round of notices. Qualcomm has already announced price increases for its Snapdragon platforms effective September 1, citing memory costs and supply chain pressure, and analysts expect the combination of memory, foundry and passive component inflation to raise the bill of materials for a typical phone by the most in years.
The pass-through math is straightforward for the industry and painful for consumers. A flagship phone carries more than a thousand MLCCs, and premium models with multiple camera modules and fast charging use more of the high-capacitance, high-reliability grades that are tightest. A 30% increase on the component bill adds only a few dollars to the cost of a single device, but when capacitor, memory, foundry and modem prices all rise in the same quarter, phone makers have little choice but to raise prices or cut features. The August notices will show up in holiday-season price tags.
The squeeze is a useful signal about the AI boom’s breadth. The narrative has focused on GPUs, HBM and power, but the components that make those systems work, capacitors, resistors, connectors, are where the demand pressure shows up second. The MLCC price hikes suggest the AI buildout is now straining parts of the supply chain that never participated in previous semiconductor cycles, and that the cost of the boom is being passed along to every device with a circuit board. For the capacitor makers, the arithmetic is finally running their way. For everyone else, the notices arriving this month are the beginning of a more expensive year.
