This kind of capacitor is also suitable for various power modules, such as high power rectification circuit, motor drive circuit, high power driver circuit, inverter, etc. Furthermore, it is suitable for many interactive energy storage circuits (such as telecom, power grid, etc.) input/output filters, inverter starting capacitors, railway power supply, industrial power supply, and UAV power and other fields.

Working Principle

EEV-FK1A151P adopts non-solid electrolyte and metal foil as electrodes. The non-solid electrolyte is composed of solvent and polar material, usually in a saturated state. When the voltage is applied to the capacitor, the electrical field lines cause polarization of the electrolyte molecules, resulting in the formation of a polarized double-µ layer, which acts an as insulating layer and prevents leakage current. At the same time, it also increases the current capacity of the capacitor. The metal foil served as electrodes, allows current to flow through electrolyte during electron-transfer process and capacitors then store energy.

Conclusion
