Why Murata, TDK, KEMET, and Yageo Allocation Is Tightening
After two years of relative balance, passive component lead times are climbing back into allocation territory. MLCC lead times at Murata and TDK have stretched past 30 weeks for high-CV automotive-grade parts, with resistor and inductor lines from YAGEO and Bourns following the same pattern. AI server build-outs, EV production ramps, and the rebuilding of safety stock at major contract manufacturers are all pulling from the same finite passive supply.
The current passive crunch differs from 2018 and 2022 in one important way: it's concentrated in specific case sizes and dielectric grades, not across the entire category. Standard 0402 X7R MLCCs in low CV values are still readily available. The pain is in high-CV automotive-grade and high-voltage Class II parts in 0603, 0805, and 1206 — exactly the components that ride along with every EV onboard charger, AI server power supply, and 800V automotive inverter design.
Industry data shows MLCC capacity expansion lagging end-market demand by roughly 18 months. Murata and TDK have committed to multi-billion-dollar capacity additions, but cleanroom construction and equipment qualification cycles mean meaningful relief doesn't land until late 2026 at the earliest. In the meantime, buyers face the same dynamic they hit during the 2018 cycle — paying spot pricing through brokers for the constrained values while distributor lead times push past 40 weeks.
