Our IGBT capacitors are perfect for power semiconductor circuits, high current, high voltage, high pulse applications, IGBT modules, multiple lead styles, snubber, energy conversion, power semiconductor circuits, electric vehicles, UPS, alternative energy power, management systems, switch mode all power supplies, power supplies, and motor controllers.

Qiyutech, the certified manufacturer of all high and low voltage capacitors. Designed by only experienced professionals, these high-performance snubber capacitors are suitable for high voltage current operations. Our IGBT capacitors provide reliable protection against all transient current voltages which are produced by high dI/dt in power electronics. These are also helpful in minimizing power dissipation and deliver unparalleled performance characteristics. Additional specifications include; low ESR (low series resistance) and ESL (minimum series inductance), 0.1~5.6μF Capacitance, -40~+85/105℃ temperature range, and non-inductive dielectric polypropylene winding.

Side by side pre-listed capacitors, we are specialized in customizing capacitors, terminal styles, and alumium cases according to your requirements. And all capacitors of Qiyutech are RoHS compliant.
