Film Capacitors

Film capacitors, also known as plastic film capacitors, are non-polarity capacitors with an insulating film filled with electrostatic capacity as the dielectric. Unlike ceramic, mica, and other capacitors that use crystalline solids as the dielectric material, the dielectric material of the film capacitor is a dielectric film composed of polyester, polypropylene or other dielectric polymer materials. Besides its long life capability, plastic film capacitors have other unique advantages which attract them to be widely used in industry.

BFC2373FM684MF Applications and Working Principle

BFC2373FM684MF is a plastic film capacitor made by Shenzhen BAYKE Electronics Co., Ltd. It is a non-polarized capacitor featured with an axial lead, radial structure, and plastic package. This type of capacitor has a wide range of applications in consumer, industrial, and automotive electronic products, such as circuits of Fluorescent Ballast, choke, compressor motor, and servo. Its main working principle is that it can store electric energy when the electric field is applied. During the electrical charging process, the positive and negative pole charges of the capacitor store electric energy, thus forming a non-linear voltage-current characteristics.

The applied voltage divided by the capacity of the capacitor is called the capacitance of the capacitor. The capacity of BFC2373FM684MF is 68μF (micro Farads). When a 65V AC voltage is applied, the current will be 9.18mA (milliamp). If the applied voltage is large enough to exceed a predetermined value, the AC current will pass through the capacitor, and the electric field between the capacitor plates will increase with the increase of the applied voltage, thus increasing the voltage loss of the capacitor. Once the applied voltage is larger than the breakdown voltage, the breakdown of the capacitor will occur and cause the capacitor to be damaged.

In addition, the working temperature of BFC2373FM684MF is -40°C~105°C, and the insulation resistance is 10,000 megohms. It has a wide range of applications and offers zero-voltage switching, distortion reduction, and filtering functions. The overload protection of this capacitor type is 10 times in excess of the rated voltage. It is fully equipped with double seals and an outer copper coating, providing extra protection to the capacitor\'s delicate core. Moreover, it is comparatively compact and lightweight, making it easier to integrate into audio and video circuits.

Conclusion

In conclusion, BFC2373FM684MF plastic film capacitors are featured with long life ability and working stability, making them preferred choice for many industrial and automotive applications. Its overload protection and zero-voltage switching make it a reliable capacitor for the circuits, ensuring the safety of the product. Besides, the insulation resistance and working temperature are adequate for its different applications.
