DC Support Capacitor Benefits
DC support capacitor is capable of supporting higher voltage more than normal capacitors. So it is suitable for dc power filter and high voltage dc transmission.
Its low loss feature make it is resultful to work as store and release electrical energy, as well as increase efficient and performance of the system.
By applying for high-quality insulation material and stable dielectric, we make it’s reliable capacitance value and low ESR.
Even in high frequency ranged dc support capacitor performed good, keep its capacitance value stable and low ESR, such as power electronics, communication devices etc.
