Film Capacitors

Film capacitors, also known as plastic film capacitors, film dielectric capacitors, polyester capacitors or paper capacitors, are electronic components extensively used for signal filtering, decoupling, energy storage, timing and other purposes in power supplies, and are also important components in audio and hi-fi applications. Common types of film capacitors include polyester film capacitors, polypropylene film capacitors, and Teflon film capacitors.

683PSB302K2J Film Capacitor Applications

The 683PSB302K2J is a series of polyester film capacitors manufactured by Cornell Dubilier and characterized by a reliable and consistent performance. These capacitors offer a voltage rating of 630 Vdc, a capacitance range of 0.22-1 uF, and a rating temperature of 85°C. The 683PSB302K2J capacitors are also resistant to diffusion, in addition to offering low temperature coefficient and good electrical stability. As a result, these capacitors are commonly used in AC filter circuits, output coupling and bypass circuits, and other general purpose applications.

683PSB302K2J Working Principle

The 683PSB302K2J film capacitor consists of two metal plates that are separated by an insulating material, referred to as the dielectric, which can be a polyester film. Electrical energy is stored in the form of an electric field between the two plates when a potential difference (voltage) is applied to the capacitor. When the supply voltage is removed, the capacitor continues to conduct electricity. This is because the electrical field, generated by the applied voltage, continues to provide the transfer of charge between the two plates, allowing current to flow within the capacitor.

Conclusion

In conclusion, 683PSB302K2J film capacitors are widely used for a variety of applications due to their reliable and consistent performance. Furthermore, these capacitors offer a voltage rating of 630 Vdc, a capacitance range of 0.22-1 uF, and a rating temperature of 85°C. Finally, the working principle of these capacitors is based on the electrical field between two metal plates separated by a dielectric material, such as polyester film.
