F339X121548MD02W0

Introduction

F339X121548MD02W0 is a type of film capacitor. Film capacitors are generally considered safer and less prone to rupture than ceramic capacitorsbut are physically larger. This type of capacitor comes in both radial and axial packages.

Application Field

F339X121548MD02W0 is mainly used for AC motor starting and running applications, for general instrument, vibration suppression, and power entry module or power factor correction circuits. Furthermore, it can be utilized in electronic ballasts and other electronic circuits.

Working Principle

The film capacitorconsists of a metalized PET film rolled up to form a cylindrical capacitor with a metal plate on each side. The plate is then soldered to one end of the metalized film. When a voltage is applied across the plates, a very thin dielectric film is formed between them. This dielectric film is extremely thin and can provide very high levels of capacitance in a small package. When the voltage is removed, the dielectric film collapses and the excess charge is dissipated. This process is what makes film capacitors so effective.

Film capacitors can be classified into two different types: film-foil capacitors and film-filled capacitors. Film-foil capacitors consist of a metalized film electrode placed between two metalized aluminum foils. The metalized film electrode is usually silver or gold, and the metalized aluminum foils consist of silver or aluminum. Film-filled capacitors are made using PET or PEN film electrodes and are filled with a liquid or gas. These types of capacitors are usually used for applications where high levels of capacitance are required in a small area.

Conclusion

In conclusion, F339X121548MD02W0 is a type of film capacitor that is mainly used for AC motor starting and running applications, general instrument, vibration suppression, power entry module or power factor correction circuits and in electronic ballasts. The film capacitor consists of a metalized PET film rolled up to form a cylindrical capacitor with a metal plate on each side.
