MLCC High-Cap Shortage: AI Servers Eat Capacity, Passives Follow
Status / Timeline
MLCC is the "rice of industry" — the most used basic component. This round is different: the tight parts are not commodity grades but the once-niche high-capacitance, high-voltage types.
| Dimension | Change | Scope |
|---|---|---|
| Price trigger | Murata led the increase in April; Samsung Electro-Mechanics, TDK, Taiyo Yuden followed | Japanese high-cap leads |
| Increase | Some high-cap, large-size channel prices +15%–35% | Spot jumps |
| Spillover | YAGEO IT lines flooded with overflow orders, utilization surged | Taiwanese makers follow up |
| Gap spread | Networking / industrial buyers stock in millions; MOSFET now sourced in tens of millions | All passive categories linked |
Tightest now: ① AI server / data-center high-cap MLCC (10µF+, large size, high voltage, high Q); ② automotive high-cap (powertrain / ADAS domain controllers); ③ high-end mid-voltage large-cap (GPU board power filtering, networking). For buyers — high-cap is hard to get, generic mid/low-cap lead times have stretched, and the next wave of passive price hikes is on the way.
Why This Is Happening
- AI servers rewrite demand math a standard server uses ~2,000 MLCCs; one AI server exceeds 20,000, and an NVIDIA Rubin rack holds 90,000+; a high-end MLCC consumes 3–5x the capacity, swallowing mature capacity in one gulp
- Japanese duopoly controls supply Murata and Samsung Electro-Mechanics hold ~90% of AI high-cap share at 95%+ utilization; capacity is prioritized for high-margin AI parts, squeezing standard 0402/0603 mid/low-cap
- Materials and certification raise short-term barriers nano-scale barium titanate powder has a hidden bottleneck and expands slowly; automotive / AI certification takes 12–18 months, so substitution is hard near-term — the Japanese-first, Korean/Taiwan-follow move is forced by structural shortage, not a deliberate price hike
Impact on Buyers
Automotive (powertrain / ADAS), AI server power, and networking equipment are hit first; consumer electronics, appliances, and generic industrial 0402/0603 will follow. Networking and industrial buyers are stocking for the H2 peak season, widening demand further.
What Buyers Should Do
- Lock high-cap early re-evaluate BOM and lock volume now for 10µF+ large-size automotive / AI-server-grade MLCC before lead times also rise
- Develop second sources evaluate YAGEO, Walsin, Fenghua, Samsung Electro-Mechanics alternatives to cut single-source risk
- Put resistors / inductors on watch history shows MLCC leads, resistors/inductors follow; the passive linked-price window is open, prepare early
Frequently Asked Questions
Recommended Part Numbers / Categories to Watch
- High-cap MLCC: 10µF+ / large size / automotive-grade / AI-server-grade (Murata, Samsung Electro-Mechanics, TDK, Taiyo Yuden)
- Generic mid/low-cap: 0402 / 0603 common values (YAGEO, Walsin, Fenghua, Samsung Electro-Mechanics)
- Linked passives: automotive resistors, power inductors, tantalum caps (next in the spread)
