Investor enthusiasm links MLCCs to booming AI server demand, with commentators and some suppliers warning of tight high-end capacity and huge per-server MLCC counts. Analysts highlight leaders like Murata and Samsung, and Chinese firms pushing localization and new high-voltage, high-capacitance lines to capture data‑center orders. However, disclosures from Twin Star New Materials and 昀冢科技 stress their MLCCs are currently focused on consumer and automotive electronics, not AI compute servers, and that the business remains small or loss-making with long payback cycles. The trend underscores a gap between market expectations and many firms’ present capabilities and revenues.
Tech professionals must separate investor hype from component realities to plan procurement and system design. Misjudging MLCC availability or specs for AI servers can disrupt data center buildouts and supplier strategies.

Twin Star New Materials disclosed that recent stock-price abnormality followed two trading days with cumulative gains over 20%. The company said MLCC (multilayer ceramic capacitor) products currently contribute under 1% of overall revenue; its MLCC release films target consumer and automotive electronics and are not used in AI compute servers. Management warned the MLCC line has minimal short-term impact on results and urged investors to assess risk. The statement aims to explain share volatility and clarify the scale and market focus of the new MLCC business amid investor attention to semiconductor-related product lines.
昀冢科技 disclosed that its MLCC (multilayer ceramic capacitor) business is still loss-making, with large upfront investment and long payback cycles, and warned investors about risks from intensified competition or shifting downstream demand. The company noted its MLCC products are currently used mainly in consumer electronics and have not been deployed in AI compute servers. The disclosure followed an abnormal stock-price surge across three trading days in May 2026. The statement is intended to caution investors about project returns and market uncertainty.
AI server demand is driving a surge in multi-layer ceramic capacitor (MLCC) requirements, with a typical AI server needing roughly 15,000–25,000 MLCCs and stricter specs for high frequency, capacitance, voltage and temperature tolerance. While Japanese and Korean firms like Murata and Samsung Electro-Mechanics still lead high-end AI-grade MLCCs, several Chinese A-share companies are expanding into the AI supply chain and advanced materials. Sanhuan Group is highlighted as a domestic MLCC leader, launching high-voltage, high-capacitance series (e.g., 0805-105-100V) to address power management around high-performance GPUs/TPUs, improving market share in networking and servers and positioning to capture AI server localization orders. This matters for hardware supply chains, localization and data-center buildout.
@kugo_A10: MLCC全球超级缺货。AI服务器、车用电子把高端产能全抢光。 明年之前看，都会是卖方市场。 前几天拿了点风华高科底仓。 这个方向，感觉有点搞头。 梳理了下受益的几家公司：风华高科、三环集团、国瓷材料。
