Film Capacitors

Introduction

Film capacitors, also called plastic film capacitors or plastic film dielectric capacitors, are made of metallized plastic films, making them a kind of electrostatic capacitor. As the most important part within passive components, film capacitors can be used in a wide range of applications, such as electromagnetic interference, signal processing, amplification and filtering, voltage stabilization, energy storage, oscillation and resonance and so on. In fact, film capacitors rarely exhibit a value that can be precisely predicted by their electrical parameters. Their actual value, as well as their failure modes, depend on their peak voltage rating and environmental conditions during usages. Among film capacitors, the B32529C1682J289 is one of the most widely used ones.

B32529C1682J289 Application Field and Working Principle

Application Field

B32529C1682J289 is developed and manufactured by EPCOS, a subsidiary of TDK, which is a world-leading film capacitor. It is mainly used in signal processing and amplification in audio systems, telecom and communication devices, information technology equipment, medical equipment, power supplies, high power UPS, etc. In addition, its good high-frequency characteristics also make it suitable for high-frequency stabilizing circuits and HF filter feeding circuits.

Working Principle

The B32529C1682J289 is a high-precision, reliable and durable film capacitor. It uses a plastic film based dielectric called polyester or mylar as the insulating material between the conductors, which gives the capacitor the ability to store energy when a voltage is applied to it. The stored energy is proportional to the applied voltage. This capacitor consists of two conductors which are separated by a thin dielectric layer. When a voltage is applied, the capacitance occurs due to the electrostatic field generated between the conductor and the dielectric. This capacitor has a very low leakage current, ensuring that there is no loss of energy.

Conclusion

The B32529C1682J289 is a film capacitor designed and made by EPCOS and has many applications in signal processing and amplification. Its dielectric is made of polyester or mylar and is used to store energy when a voltage is applied. It has a low leakage current and is highly reliable and durable. Therefore, it is one of the most widely used film capacitors and has become the best choice for many products in different fields.
