Film Capacitors

Film capacitors are an important type of capacitor used in many modern circuits. They are used in a wide variety of applications from scientific and industrial instruments to consumer electronics. The 947D801K901BLMSN film capacitor is one of the most popular film capacitors on the market today.

947D801K901BLMSN application field

The 947D801K901BLMSN is a non-inductively wound film capacitor rated at a nominal working voltage of 0.25V. It is used primarily in switched-mode power supplies, resonant inverters, converters and low distortion audio amplifiers. It has a wide operating temperature range and low Equivalent Series Resistance (ESR) compared to other film capacitors, making it an ideal choice for many applications.

947D801K901BLMSN Working Principle

The 947D801K901BLMSN works by storing electrical energy in a thin dielectric film such as polyethylene, polypropylene, teflon, etc. The dielectric film is sandwiched between two metallic plates, creating a "sandwich effect". When an electrical current is applied to the capacitor, the electric field produced by the current causes the electric charge to migrate from one plate to the other, thus creating the capacitance. The capacitance is then determined by the geometry and thickness of the dielectric film, and the plates themselves.

Conclusion

The 947D801K901BLMSN film capacitor is an excellent choice for a wide range of applications. With its low ESR and wide operating temperature range, it is an ideal solution for many power supply and power management applications. Furthermore, its excellent performance and reliability make it a popular choice for both commercial and consumer applications.
