Film Capacitors

Film capacitors are known for their extremely precise and high temperatures i.e. up to +150°C, and accordingly they are used in applications such as switched mode power supplies (SMPS) and motor drives. At temperatures below +85°C film capacitors permit a remarkably stable temperature coefficient.

170474J160HC Capacitor Application Field and Working Principle

The 170474J160HC capacitor is one of the most popular film capacitors available in the market today with its small size, high precision and high temperature resistance properties. It is especially suitable for applications such as high frequency line filters, LED drive circuits, switching power supply etc. Below is an explanation of the application field and working principle of this film capacitor.

Application Field: This capacitor is mainly used in SMPS, LED driver circuits, high frequency line filters, and other power supplies requiring ultimate reliability. It is also commonly used in switches, motor drives, audio, ultrasonic, and radio frequency circuits.

Working Principle: The working principle of a film capacitor is similar to that of an electrolytic capacitor. It is made up of a dielectric film which is rolled up and placed between two electrodes. The thinner the dielectric film, the less capacitance is created. The dielectric film acts like a common insulator, while the two electrodes charge with opposite polarity and store energy.

The capacitance of the 170474J160HC capacitor is measured in Farads and this is represented by the letter “Q”. The higher the Q value, the higher the capacitance of the capacitor. Also the film capacitor comes with very low ESL and ESR values, which is an important parameter for high frequency applications. The maximum operating temperature of the capacitor is specified as 150°C.

In short, the 170474J160HC film capacitor is an ideal choice for applications where high precision and high temperatures are required, and it is a high quality and reliable standard component for most of the essential applications.
