Film capacitors also known as plastic film capacitors, film dielectric capacitors, are classified as an alternative to the traditional method of capacitor construction by winding layers of metalized paper onto a plastic bobbin. Compared to traditional paper/plastic film capacitors, B32672L1622K000 has a higher voltage rating, larger capacitance and longer life expectancy.

Application Field

B32672L1622K000 film capacitors are mainly used in telecommunications, radar, computer, television and welding system etc. They are characterized by good electrical stability, reliable performance, and long service life.

Working Principle

B32672L1622K000 film capacitors are constructed by embedding an insulating film between two metal plates, forming two-terminal, parallel-plate capacitors. As the insulating film is very thin, virtually no volume and weight are consumed.

When a voltage is applied across the two metal plates, electrical charges are separated, creating an electric field between the plates. The electric field stores the energy that corresponds to the charge stored on the plates. This energy can then be released when the applied voltage is removed.

Due to its low equivalent series resistance and excellent frequency behaviour, film capacitors perform well in high frequency filter circuits as well as applications with overload voltage spikes. Film capacitors offer superior temperature stability, with their capacitance typically varying by only 2% over a temperature range of -40°C to +85°C.

Conclusion

B32672L1622K000 film capacitors are ideal for use in demanding AC and DC applications such as power supplies, digital cameras, medical devices, professional audio equipment, and automotive controllers. Due to their thin dielectric, low ESR and distributed capacitance, these capacitors offer superior performance over paper/plastic film capacitors in high frequency applications.
