Film Capacitors

Film capacitors, sometimes called plastic film capacitors, are capacitors composed of a thin film of plastic or polymer film that offers a greater operating temperature range than paper capacitors and superior dielectric strengths. Film capacitors are used in a wide variety of applications; from general-purpose AC applications to pulse-discharge and radio frequency applications.

The 947D311K132BHMSN film capacitor is a film capacitor produced by Kemet. Its primary application is as a low voltage semiconductor device for power supply decoupling. The device is designed to have a low ESR; due to its construction, it is capable of providing a smooth voltage response, even when subjected to rapid voltage changes.

Working Principle

Film capacitors function as energy storage devices. The 947D311K132BHMSN works by storing electrical charge on its plates. When a voltage is applied to the capacitor, current flows from the positive plate to the negative plate, and the capacitor charges. When the voltage is removed, the stored energy is released, providing a steady voltage to the power supply.

The 947D311K132BHMSN’s low ESR, or equivalent series resistance, is one of its key features. This device has an ESR of only 0.08 ohms. This low resistance allows the capacitor to quickly respond to rapid voltage changes, resulting in greater noise suppression and improved power supply reliability.

Application Field

As mentioned above, the 947D311K132BHMSN is primarily used as a low voltage semiconductor device for power supply decoupling. In this application, the capacitor provides a reliably smooth voltage response in the face of rapid voltage swings. This makes it ideal for use in applications such as computer mainboards and consumer electronics.

The 947D311K132BHMSN is also suitable for use in medical, military, and aerospace applications. Its low ESR and high resistivity make it an ideal choice for high frequency power supplies.

In addition, the 947D311K132BHMSN is capable of providing low capacitance values at higher temperatures. This makes it particularly suitable for use in automotive applications, where temperatures are often high.

Conclusion

In conclusion, the 947D311K132BHMSN is a high-quality film capacitor suitable for a variety of applications. Its low ESR, high resistivity, and low capacitance values make it an ideal choice for power supply decoupling, medical, military, and automotive applications. It is also noted for providing reliable and smooth voltage response in the face of rapid voltage swings.
