China MLCC supply chain races to scale amid AI server boom
Synopsis
Key Takeaways
China's upstream supply chain for multilayer ceramic capacitors (MLCCs) — the miniature passive components often called 'the rice of electronics' — is aggressively expanding capacity as artificial intelligence-driven demand triggers a record surge in global orders, with major domestic suppliers reporting double-digit revenue growth heading into the second half of 2026.
Sinocera signals output surge ahead
Shandong Sinocera Functional Materials, one of China's leading suppliers of dielectric powder to MLCC manufacturers, disclosed in a Shenzhen Stock Exchange filing on Wednesday, August 6, 2026 that it is actively scaling capacity to serve AI server and automotive markets, with portions of its new production lines already operational. The company reported sales growth of nearly 17 per cent year on year in the first half of 2026, reaching 2.5 billion yuan (approximately US$370 million), while net income climbed 9 per cent over the same period.
'Looking ahead, as new capacity gradually ramps up, output and sales of MLCC powders are expected to rise further,' Sinocera said in the filing, adding that it would continue to expand and ensure its supply aligns with market momentum. Dielectric powder is the core raw material inside MLCCs, which regulate electrical currents across devices ranging from smartphones to high-performance AI hardware.
Why it matters: the 'largest and longest' MLCC cycle
Goldman Sachs has described the current phase as the 'largest and longest' cycle in MLCC history, underpinned by the insatiable computing requirements of AI infrastructure. Each high-density AI server rack can contain thousands of MLCCs, multiplying demand well beyond what consumer electronics cycles historically generated. The component's ubiquity across power regulation, signal filtering, and decoupling functions makes it a critical bottleneck when supply lags.
Global MLCC production has long been dominated by Japan's Murata Manufacturing and South Korea's Samsung Electro-Mechanics, but Chinese upstream material suppliers — including dielectric powder and nickel powder makers — are positioning themselves as indispensable links in the value chain as demand outpaces incumbent capacity.
Broader investment wave across upstream suppliers
Other upstream MLCC material suppliers have also moved quickly to commit capital. Companies including Jiangsu Boqian New Materials, a nickel powder supplier, and electrode material maker Chaozhou Three-Circle are among those reportedly pouring investments into new capacity to meet the accelerating order flow. The coordinated expansion signals that the supply response is broad-based rather than isolated to a single firm.
According to industry analysts, the upstream buildout reflects confidence that AI infrastructure spending — particularly in AI server clusters — will sustain elevated MLCC demand through at least the medium term, with research firm Frost & Sullivan among those tracking the sector's structural shift.
What's next
The pace at which Sinocera's new production lines reach full utilisation will be closely watched as a leading indicator of whether China's domestic MLCC supply chain can keep pace with accelerating global AI hardware deployments. Any capacity shortfall at the material level could ripple upstream into finished MLCC pricing and, ultimately, AI server build schedules — making the sector a bellwether for the broader AI infrastructure cycle.
