High-Capacity DC Support Capacitor from China Suppliers - Reliable Factory Solutions for Power Conversion & Energy Storage
DC support capacitor benefits
-
♢
High-voltage withstand ability: 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.
-
♢
Low loss: 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.
-
♢
Long-lifespan: By applying for high-quality insulation material and stable dielectric, we make it’s reliable capacitance value and low ESR.
-
♢
Good frequency response: 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.
