Introduction

Film capacitors, sometimes also known as plastic film capacitors, are widely used in applications ranging from household electronics to audio/video productions. Model 947C391K102CCM is the latest innovation in this type of capacitor technology and is designed for a variety of applications. This paper will discuss the application fields and working principle of 947C391K102CCM film capacitors.

Application Field and Working Principle

The 947C391K102CCM film capacitors are designed to offer a wide range of application fields. These include automotive, telecommunications, power suppression, high temperature motor control, commercial electronics, audio/video, medical imaging, etc. The capacitor is ideal for use in circuit designs that require reliable performance, efficient power delivery, and good surge and heat dissipation.In terms of working principle, the 947C391K102CCM film capacitor is a four-terminal device which allows for voltage to be applied at one end and current to be drawn from the other end. The voltage and current will each be stored in the capacitor, which is made of plastic foil material. The 947C391K102CCM film capacitors use an electrolytic-filled polyester film as the dielectric, providing excellent electrical characteristics and reliability.The capacitor has a high temperature resistance, long life, and remarkable energy storage performance due to its excellent insulation characteristics. The film also offers higher insulation resistance, allowing for stable and precise condenser characteristics even at high temperatures. Moreover, the 947C391K102CCM film capacitors are equipped with a flame-retardant terminal design, making them able to maintain their insulation performance even under extreme environmental conditions.The capacitors feature good self-healing properties, meaning that the dielectric will automatically close and heal after a surge or electric breakdown. This ensures that the film capacitor can retain its stability and performance under harsh conditions. The 947C391K102CCM film capacitors also have low ESR (equivalent series resistance) and low ESL (equivalent series inductance), making them ideal for use in applications that require clean power delivery.

Conclusion

In summary, the 947C391K102CCM film capacitors are designed for a wide range of application fields and have excellent electrical characteristics. The capacitor has superior insulation performance, self-healing properties, and excellent stability, making them ideal for use in demanding applications. The 947C391K102CCM film capacitors are also equipped with a flame-retardant terminal design, further enhancing their performance and reliability.
