Introduction of Film Capacitors

Film capacitors are type of capacitor which mostly uses plastic film as the dielectric material. Film capacitor can be manufactured with good longterm stability and high accuracy. It provides a very high insulation between layers which gives higher levels of dielectric strength and other electrical properties. Film capacitors are usually much smaller than other capacitors, therefore they are most often used in electronic equipment where space saving is an important consideration.

ECQ-E2473JFB Application Field and Working Principle

ECQ-E2473JFB, a film capacitor, is designed for use in AC current suppression, DC blocking and high frequency smoothing applications. Its dielectric is Metallized Polypropylene Film, which disconnects and reduces high frequency radio signals and noises effectively and provides high temperature, humidity and better stability with respect to mechanical vibration.The working principle of the ECQ-E2473JFB is similar to that of other film capacitors. It is made up of two small conductive plates and a dielectric material that separates the plates. When a voltage is applied to the plates, an electric field is formed in the space between them with the plate closest to the positive terminal of the applied voltage becoming positively charged and the plate closest to the negative terminal becoming negatively charged. This creates a potential difference between the two plates.A current can flow between two plates if a conductive pathway is created. The current is able to travel between the two plates because the dielectric material is an insulator and the electric field created by the voltage prevents the current from travelling directly between the two plates. This is how the film capacitor works and is the same regardless of the type of capacitor being used.

Conclusion

In conclusion, ECQ-E2473JFB is a film capacitor based on Metallized Polypropylene Film and designed for AC current suppression, DC blocking and high frequency smoothing applications. Its working principle is similar to that of other film capacitors, in which an electric field is created between two small conductive plates and the current is able to travel between the two plates because the dielectric material is an insulator.
