Film Capacitors

Film capacitors, also known as dielectric capacitors, are passive electronic components made from a thin layer of dielectric material, usually metal-filled plastic, between two electrodes. Theses capacitors are commonly used for filtering, coupling, decoupling, and signal processing in many electronic applications. They provide excellent electrical insulation, high stability, low losses, and long-term reliability for applications involving high frequencies and voltages. The BQ074E0224K belongs to this type of capacitors and this article will discuss its application field and working principle.

Application Field

The BQ074E0224K is an appropriate choice for small electronic devices, such as mobile phones, VCRs, and digital cameras. This capacitor is de-signed for operating at high frequencies, voltage, and temperature. It can meet the requirements of attaching circuits, signal processing, filters, and radio switching systems that require capacitors with low ESR (Equivalent Series Resistance). It is also suitable for audio and video circuits, power circuits, frequency modulation circuits, and surge suppression. This capacitor has a wide range of applications in various electronics devices.

Working Principle

The BQ074E0224K is a type of film capacitor that works on the principle of dielectric. It is made up of a thin layer of dielectric material between two metal electrodes. When a voltage is applied across the electrodes, an electric field is set up. This electric field reduces the free electrons in the dielectric material which results in a charge on the electrodes. This charge is stored in the capacitor and can be released when the voltage is removed from the electrodes. The higher the dielectric voltage, the higher the charge stored in the capacitor.

The BQ074E0224K is a high-performance capacitor with excellent electrical characteristics. It supports frequencies up to 160MHz and has a high temperature coefficient of capacitance. It is designed with an additional positive temperature coefficient to provide improved characteristics in high temperature applications. The low ESR and high surge current capabilities of this capacitor make it ideal for capacitor-input power supplies, high output switching power supplies, and battery operated devices.

Conclusion

The BQ074E0224K is a type of film capacitor commonly used for filtering, decoupling, and signal processing in many electronic applications. It is suitable for applications involving high frequencies, voltages, and temperatures, such as attaching circuits, signal processing, filters, radio switching systems, audio and video circuits, power circuits, frequency modulation circuits, and surge suppression. This capacitor provides excellent electrical insulation, high stability, low losses, and long-term reliability. In addition, it supports frequencies up to 160MHz and has a high temperature coefficient of capacitance.
