Film Capacitors

A film capacitor, also known as plastic film capacitor, is a type of capacitor made with plastic film as an insulating dielectric. It covers a wide range of capacitances from picofarads (pF) to microfarads (μF). It can be further divided into two general categories, which are washer-type capacitors and axial capacitors. Most film capacitors these days are axially wound. Popular materials used as insulation for film capacitors include polyethylene terephthalate (PET or Mylar) and polypropylene (PP). There are also two general categories for film capacitors, which are AC Applications and DC Applications.

B32923C3155M000 Application Field and Working Principle

The B32923C3155M000 is a high-voltage film capacitor made with a polypropylene dielectric. It has a wide temperature range of -40°C to +85°C and an operating voltage of 3.15kV, making it a great choice for high-voltage, high-temperature applications. This device is also highly reliable due to its long life and low ESR.

The B32923C3155M000 is used in applications such as power supplies, high-voltage electric motors, frequency converters, switch mode power supplies and motion control devices. It is also used in motor field applications such as electric traction, elevators and air handling equipment.

The operating principle of the B32923C3155M000 is quite simple. Its dielectric material forms a layer of insulation between the metal plates of the capacitor. As voltage is applied to the metal plates, an electric field is generated, creating a charge imbalance which creates a current flow across the metal plates. This current is stored as electric energy in the form of a charge on the capacitor plates.

The capacitance of the B32923C3155M000 is determined by its physical size, the dielectric constant of its insulation material, and the distance between the plates. As the capacitance increases, the current flow will be higher, allowing for larger voltage and current levels.

The B32923C3155M000 is an excellent choice for high-voltage, high-temperature applications, as it can handle large voltage levels while maintaining its reliability. Its long life and low ESR also make it a great choice for motor field applications.
