Film capacitors or film dielectric capacitors are passive electronic components used in several applications. These components are generally constructed using the plastic film as dielectric, and the electrodes are usually made of aluminum or a metallic foil. ECW-H12303HVB, one of the most commonly used film capacitors, is designed and manufactured specifically for AC and DC power supplies applications. It has excellent electrical characteristics such as low dissipation factor, low ESR, and high insulation resistance.

The ECW-H12303HVB capacitor is available both in surface mount and through-hole mount configuration. It is constructed using a polypropylene film as the dielectric materials and aluminum as the electrodes. The aluminum electrode is lead-free, thus provides increased safety during operation. It features a flat construction, which makes it suitable for high density circuitry.

The working principle of the ECW-H12303HVB is quite simple. When a voltage potential is applied across the terminals of the capacitor, the electric field generated between the electrodes will attract the free charges from the surrounding area. As the free charges are attracted towards the surface of the electrodes, an electrostatic capacitance is created. This capacitance will then store the electrical charge and the current required in the specified circuit.

The ECW-H12303HVB capacitor is mainly used in a variety of AC and DC power supplies applications. It can be used in a wide variety of applications like power conditioning, timing circuits, AC / DC converters, motor drives, switching power supplies and energy storage systems.
