The deal highlights how AI server demand is reshaping the market for tiny but essential electronic components
Samsung Electro-Mechanics, the world’s second-largest producer of multilayer ceramic capacitors, just locked in a 454 billion won contract to supply MLCCs to a global firm. That’s roughly $320-360 million worth of components most people have never heard of, powering technology most people use every day.
What are MLCCs, and why should you care #
Multilayer ceramic capacitors are tiny components, sometimes smaller than a grain of rice, that stabilize power delivery and filter out high-frequency noise in circuit boards. A single AI server can require between 15,000 and 25,000 MLCCs. MLCCs destined for AI server applications reportedly command prices more than triple those for ordinary consumer electronics uses.
Samsung Electro-Mechanics, commonly known as SEMCO, holds over 20% of the global MLCC market. That makes it the second-largest producer worldwide, trailing only Japan’s Murata Manufacturing.
SEMCO’s broader strategic play #
The company also confirmed a separate contract for silicon capacitors valued at 1.5 trillion won. That deal, reportedly signed on May 20, 2026, dwarfs the MLCC order.
SEMCO is forming a joint venture with Japan’s Sumitomo Chemical to produce glass substrates, a partnership valued at around 500 billion won.
The company is also rolling out ultra-high-capacitance MLCCs designed for automotive applications.
What this means for investors #
The 454 billion won MLCC contract alone would represent roughly 10% of SEMCO’s component division revenue from the previous year.
The speculated buyer for this contract is a major US tech firm, with market observers pointing to leading hyperscalers such as Google, AWS, or Meta as likely candidates.
