It is used in automotive and industrial applications, and is also used in many consumer products. Additionally, its combination of superior stability and affordability makes it suitable for use in medical instruments, measuring equipment, and compensating for harmonic distortion in audio systems.

These capacitors are known for their ability to withstand both high temperatures and humid environments and their ability to maintain a stable, efficient performance in a variety of rugged conditions. Film capacitors are also resistant to most liquids, making them suitable for use in harsh environments.

B25620B1457K103 Working Principle

The working principle of the B25620B1457K103 capacitor is quite simple yet effective. The capacitor consists of two parallel metal plates which are separated by a thin layer of plastic film. When an AC voltage is applied to the capacitor, a steady electric field is created within the gap between the plates. This electric field causes electrons to flow through the gap, charging the capacitator.

The capacitance of the film is determined by the ratio of the size of the plate area to the distance between the two plates. A large plate area results in a high capacitance, while a small plate area results in a low capacitance. Additionally, the dielectric of the film affects the capacitance. Films with higher dielectric constants, such as polyester, result in a higher capacitance.

The B25620B1457K103 is also known for its low loss performance. This is achieved by using a thin film and making sure that the distance between the plates and the quality of the dielectric are within specified parameters. The B25620B1457K103 is capable of operating at temperatures up to 100°C and humid environments without significant degradation in performance.

Conclusion

The B25620B1457K103 film capacitor is an ideal capacitor for many applications and environments due to its stability, durability, and affordability. Its combination of low loss performance and resistance to temperature and humidity make it suitable for use in a variety of applications. Its consistent and reliable performance is one of the main reasons why it is so popular today.
