AI Demand for High-End MLCCs Drives Japan and Korea Suppliers’ Book-to-Bill Ratios to Post-Pandemic Highs, Raising Shortage Risks in 2H26, Says TrendForce

Strong AI server demand is driving record book-to-bill ratios for leading MLCC suppliers Murata, Samsung Electro-Mechanics, and Taiyo Yuden to 1.25-1.31, the highest since the COVID-19 pandemic. This surge in high-end MLCC orders for AI accelerators is crowding out supply for consumer and automotive markets, prompting early inventory building and raising shortage risks in the second half of 2026. Taiwanese and Chinese suppliers are expected to benefit from spillover demand.
