155PPA122KS

Film Capacitors

Film capacitors, also known as plastic or polymer film capacitors, are electronic components made of plastic film as an insulating medium and aluminum or zinc electrodes. These capacitors have a variety of applications and are used in most electronic products, from computers to amplifiers. Additionally, film capacitors are used for various industrial applications as safety components, providing audio filtering, power supply filtering, decoupling, blocking, and bypass roles.

155PPA122KS Application Field and Working Principle

The 155PPA122KS film capacitor is a high-performance AC-use, polypropylene, safety standard capacitor. It is mainly used in power supply lines, UPS systems, medical equipment, industrial automation systems, and other equipment requiring interference suppression. The 155PPA122KS can be used to protect against radio frequency interference (RFI) and electromagnetic interference (EMI).The operating principle of the 155PPA122KS is based on its capacitive characteristics. In an AC circuit, when voltage is applied to the two terminals of the capacitor, an electric field is generated between them, and current flows through the wire. The 155PPA122KS has a dielectric plate made of polypropylene with aluminum as the electrode on both sides. The electric field generated by this capacitor can be adjusted by changing the thickness and width of the dielectric plate and aluminum.In summary, the 155PPA122KS is a film capacitor designed to meet the needs of high-performance AC-use applications. With its polypropylene dielectric construction and aluminum electrodes, the 155PPA122KS can provide effective interference suppression for applications in power supply lines, UPS systems, medical equipment, industrial automation systems, and more.
