The single most numerous component in modern electronics is one almost no one can name: the multilayer ceramic capacitor. A smartphone contains hundreds; an electric car, thousands. And a handful of Japanese companies make most of the world’s supply — among them, a quiet specialist called Taiyo Yuden.
The component you’ve never counted
A multilayer ceramic capacitor (MLCC) is a tiny passive component that stores and smooths electrical charge — utterly essential, and used in staggering quantities. Taiyo Yuden, founded in 1950, is one of the world’s leading MLCC makers, alongside fellow-Japanese Murata and TDK and Korea’s Samsung Electro-Mechanics. It is a pioneer of multilayer ceramic technology, and a specialist in the small, high-capacitance MLCCs that pack into space-constrained mobile devices.
Why the numbers explode
Two trends are driving relentless MLCC demand. Smartphones keep adding features in shrinking spaces, requiring ever-smaller, higher-performance capacitors. And electric vehicles are voracious: a single EV can use thousands of MLCCs to manage power across its electronics, far more than a conventional car. Taiyo Yuden also makes inductors and other devices, but it is the humble capacitor — produced by the billions — that anchors its business.
Why it matters for global partners and investors
- Investors get exposure to the secular rise in electronic content per device and per vehicle, through a focused components specialist.
- Electronics and automotive makers depend on a small group of MLCC suppliers; capacity and lead times at firms like Taiyo Yuden directly affect production.
- The watch item is the cyclical nature of components demand, balanced against the structural growth from EVs and AI hardware.
Frequently asked questions
