BCF Series, BSF Series, BCS Series
Block type ceramic capacitors with high capacitance / high pressure-resistant (630V/2.2μF～50V/350μF). They achieve large ripple current capacitance by low ESR, and high frequency characteristics by low ESL. Specifications can be customized,
Inverter of electric motor (smoothing and noise reduction), power supply of telecommunication equipments/radar for aerospace industry, decoupling of high frequency power supply for RF sputtering machine etc., Machines which need long lifetime (ex: base stations, transmitters, etc.)

Comparison of Ripple Absorption Efficiency
For smoothing ability of PWM (Pulse Width Modulation) square wave (for example, switching frequency at 500kHz), block capacitors can achieve better smoothing characteristic with 100uF, compared to aluminum electrolysis capacitors 470uF. As switching frequency goes up higher, it’s possible to reduce the capacitance of block capacitors and miniaturize the size of equipments.
