Film capacitors are widely used in the electronics industry, mainly because of their superior properties compared to other types of capacitors. The 930C4W1P2K-F is a type of film capacitor, which has become increasingly popular due to its low cost and excellent performance. This article will explain the application fields and working principle of the 930C4W1P2K-F.

Application Fields of 930C4W1P2K-F Film Capacitors

The 930C4W1P2K-F is a type of polypropylene film capacitor, which is designed for use in high frequency switching power supplies, such as switched-mode power supplies (SMPS) and resonant converter applications. The capacitor\'s unique design allows it to have superior frequency characteristics, with its minimal loss up to 500kHz. Due to this, it is usually able to maintain extremely low ESR (equivalent series resistance) and a stable ripple current. It is also a non-inductive type of capacitor, meaning it is rather immune to AC effects and runs cooler in application.

The 930C4W1P2K-F is also a good choice for audio-related applications, such as sound reinforcement systems, speaker crossover networks, and power amplifiers. In addition, it is suitable for many other high-frequency applications, such as medical equipment, automotive, LCD displays, and more.

Working Principle of 930C4W1P2K-F Film Capacitors

The 930C4W1P2K-F is an electrolytic film capacitor, with a very thin metalized polypropylene film dielectric and an electrolyte impregnated into it, to increase capacitance. The inner electrodes are made up of a thin aluminum, zinc, or tantalum metal film, and the outer electrodes are a conductive plastic layer, such as Polyethylene-Naphthalate (PEN).

When a voltage is applied between the two electrodes, an electric field is created in the area, causing an electric field displacement. This displacement is what stores the electrical energy and thus, creates the capacitance. The characteristics of the 930C4W1P2K-F make it a low-loss, high-ripple current-capable capacitor.

The 930C4W1P2K-F also has a unique temperature-stabilizing feature, which makes it an ideal choice for high-power applications. With this feature, the performance of the capacitor will not be affected by temperature changes, as the relationship between temperature and capacitance is minimized.

Conclusion

The 930C4W1P2K-F is a type of film capacitor, which is widely used in many applications, particularly high-frequency and high-power switching power supplies. It has an excellent performance, with its low ESR and stable ripple current, as well as its temperature-stabilizing feature. It is also suitable for many other audio-related and high-frequency applications. This article provides an overview of the application fields and working principle of the 930C4W1P2K-F.
