Film capacitors

Film capacitors, also known as dielectric capacitors, are widely used in electrical and electronic applications and are the most important class of capacitive components in industrial applications. The BFC238026203 film capacitor is an example of this. This article will discuss the application field and working principle of the BFC238026203 film capacitor.

Application Field of BFC238026203 Film Capacitor

The BFC238026203 film capacitor has a capacitance value of 0.15-20pf, a voltage rating of 100v-250v, a temperature range of -55°C to 105°C, and a tolerance of ± 5%. It is designed for automotive audio applications, including home entertainment systems, indicators, and electronic instruments used in sound insulation control, emission reduction, and audio mechanisms. This capacitor is made with a low-loss polyester film which can reduce wave distortion and reduce the noise and oscillation effects caused by inductive and capacitive reactance. It is lead-free and RoHS compliant.

Working Principle of BFC238026203 Film Capacitor

The BFC238026203 film capacitor works on the same principle as other capacitive components. It acts as a store of electrical energy which can be released on demand. The BFC238026203 film capacitor consists of two metallic plates which are separated by a thin dielectric layer. When a voltage is applied to the two plates, the dielectric layer stores electrical energy. The capacitance of a capacitor is determined by the inverse of the area of the plates, the distance between the plates, and the dielectric constant of the medium. The BFC238026203 film capacitor is able to store more energy at higher voltages because it has a higher dielectric constant.

Conclusion

The BFC238026203 film capacitor is a versatile component which can be used in a wide range of applications. It is well-suited for automotive audio applications due to its low-loss design and the ability to reduce wave distortion and noise. Its working principle is based on the same principle as other capacitive components, storing electrical energy in a dielectric layer between two metallic plates.
