Film Capacitors

Film capacitors, also known as film dielectric capacitors, plastic film capacitors or paper film capacitors, are constructed of a thin plastic film (also called the dielectric film) coated with an electrically conductive material. They are used in many different applications and can provide an efficient, low-cost solution for many different types of applications. One such example is the ECW-H12392JV film capacitor (ECW-H).

ECW-H12392JV Application Field

The ECW-H12392JV film capacitor is a radial-lead type capacitor that is commonly used in consumer, commercial and industrial electronics. It is most often used in power supplies, audio amplification, and other power conversion circuits. As a radial-lead capacitor, the ECW-H12392JV offers a higher temperature rating than axial-lead capacitors and is designed for a durable performance. It features long-term stability and low ESR, and is suitable for use in high-power DC-DC converters and other power circuits. The ECW-H12392JV is also an excellent choice for use in high-frequency and high-temperature circuit applications.

ECW-H12392JV Working Principle

The working principle of a film capacitor is the same as that of other types of capacitors. The principle is based on the concept of electrostatics, where two conductive plates (called electrodes) are placed in close proximity to each other. A dielectric material (film in the case of film capacitors) is sandwiched between the plates and serves to separate them. When a voltage is applied to the electrodes, a charge is built up on each of them. This charge builds up an electric field between the plates, thus creating an electrical circuit. This electric field creates an impedance, which is basically a measure of the resistance the capacitor offers to changing the electric field.

The ECW-H12392JV capacitor features a metallized polyester film as its dielectric material. This film is laid between two layers of aluminum foil, absorbing any applied current and providing high dielectric characteristics. The capacitor also features a non-inductive winding pattern with copper colored flecks and a cross-linked polyethylene insulation to ensure maximum durability and performance. The device is rated for up to 1500V AC and offers a dry construction for a reliable environment-independent performance.

Conclusion

The ECW-H12392JV film capacitor is a high-quality device suitable for many different types of applications. It offers excellent temperature, reliability and low ESR characteristics, making it a great choice for commercial and industrial applications. Its rugged construction and reliable performance make it a valuable addition to many different power applications.
