Power capacitors are specialized capacitors designed to operate at higher voltages and store significant amounts of electrical energy. Power capacitors are constructed of several smaller capacitors. They consist of conducting plates separated by an insulating material (dielectric) and are used in electrical distribution systems to improve power quality by absorbing harmonic currents and providing reactive power.
Key Features:
- High Capacitance: Typically above 1 Farad, making them suitable for energy storage applications. For example, MKP DC resin top series B25690 from TDK.
- Construction: Made up of smaller capacitors (packs or windings) using aluminum foil and polypropylene film layers.
- Applications: Used to enhance power factor, reduce losses, and stabilize voltage in electrical grids.
Power capacitors have either,
- Female M6 terminal or
- M6/M10 screw/clamp
