Film Capacitors

Modern electronics come with a high demand for quality components, and film capacitors are a critical element for these components to perform with zero failure. B32794D8125K capacitors are high quality film capacitors that are designed for various applications. This article will go through their application field and working principle in detail.

Application Field

B32794D8125K capacitors offer general purpose and new generation replacement applications. They have a wide temperature range of -55°C up to +125°C and operate up to its maximum working voltage of 630 VDC. In terms of current rating, the capacitors can handle 40 A. Due to its superior load life stability and reliability, B32794D8125K capacitors are ideal for general purpose applications such as power supplies, DC/DC converters, UPS systems, inverters and motor drives. They can also be used in industrial motors, automotive and commercial applications.

Working Principle

B32794D8125K capacitors have an aluminum case and two insertable discs that are separated by a dielectric layer. The discs are insulated from the case, but still electrically connected to it. When a voltage is applied to one of the discs, an electric field is generated and the discs are charged with different electrostatic potentials. This creates a capacitance value that can store energy and still be used for a long period of time.

The capacitance value for B32794D8125K capacitors is between 63 and 100 nF and they have a low impedance and low current leakage. When a current is applied to the two discs, the charge stored in the capacitor is discharged into the load. The aluminum case also helps to keep the temperature of the capacitor stable and prevent any damage from overheating.

Conclusion

B32794D8125K capacitors are designed to provide quality and reliable performance in a wide range of applications. They have good operating temperature range, a long life-span, and can handle high-power applications. Their general purpose and new generation replacement applications make them an ideal choice for many electronics.
