Film Capacitors

Film capacitors, also known as plastic film capacitors, have a wide variety of applications in the electronics industry. Commonly used in low voltage, low power applications, film capacitors have properties that make them highly versatile devices in many areas. This article focuses on 205PSB102K6R film capacitor and its application field and working principle.

Application Field

The 205PSB102K6R film capacitor is a polyester film capacitor with a capacitance of 0.1 µF and a voltage rating of 250V, making it a highly suitable device for low voltage, low power applications. Its reliable performance is especially beneficial in applications that require high accuracy or stability, making it suitable for applications such as ac circuits and radio frequency interference (RFI) filtering. The capacitor also works well for bypass purposes, where low voltage is required. Additionally, the device is well-suited for temperature controlled applications, including temperature coefficient measuring, thanks to its stable and reproducible temperature behaviour.

Working Principle

Film capacitors work on the principle of capacitance. Capacitance is created when two electrically conductive surfaces, separated by an insulating material, are charged to opposite, yet equal electric potentials. The 205PSB102K6R film capacitor is made up of three main parts: two metalised polyester films (as the "plates"), and an insulating material (as the dielectric). When these parts are combined, there is a static electrical charge accumulated between them, forming an electrical field - the overall capacitance. The polyester film capacitors offer minimal dielectric losses, great stability, and relatively low dielectric absorption rate, making them ideal for the aforementioned low voltage, low power applications.

Conclusion

The 205PSB102K6R film capacitor is a highly versatile device suited for a variety of low voltage, low power applications. Its simple construction, featuring two metalised polyester films and an insulating material, results in minimum dielectric losses and great stability. With its various advantages and reliable performance, the 205PSB102K6R film capacitor is a great value to any electronics project.
