Film capacitors

Film capacitors are a type of capacitor consisting of conductive metal strips which are etched or deposited on the surface of a film. The two strips form the two electrical leads of the capacitor. These leads have a thin coating of insulation material, which is usually a dielectric. The dielectric film serves as the insulator between the two leads and also acts as a dielectric material in the capacitor, which determines the capacitance of the capacitor.

947D331K132ALGSN application fields and working principle

The 947D331K132ALGSN film capacitor is commonly used in power conversion applications. It is particularly well suited for high-frequency switching applications such as DC/DC converters, AC/DC power supplies, inverters, and PLL circuits. The 947D331K132ALGSN consists of two metal plates separated by a thin film. The plates are typically made from aluminum or copper and the film is usually a dielectric, such as polypropylene, polycarbonate, or Teflon. The plates and the film are held together in a plastic package.

The working principle of the 947D331K132ALGSN is relatively simple. When an AC voltage is applied to the capacitor, the negative and positive cycles of the voltage attract and repel electrons from one of the metal plates to the other, creating an electric field between the plates. This electric field is responsible for storing energy in the capacitor, which is then discharged when the AC voltage changes. The 947D331K132ALGSN has a capacitance of 3300pF (picofarads).

The 947D331K132ALGSN has a wide temperature range from -55°C to +110°C, making it suitable for applications in environments where temperatures can be extremely high or low. In addition, it has a high surge current rating of 2A, meaning it is capable of handling short, but intense current peaks in applications such as motor drives, switching power supplies, and UPS systems. Furthermore, the 947D331K132ALGSN has a long life expectancy of 10,000 hours, making it an ideal choice for long term applications.

In summary, the 947D331K132ALGSN film capacitor is a versatile and reliable capacitor which is suitable for a wide range of applications in both commercial and industrial environments. Its reliability and wide temperature range make it perfect for long term applications, while its high surge current rating and long life expectancy make it a reliable choice for short term or high power applications.
