Film capacitors, generally referred to as film caps, are electrical components that store electrical energy in the form of capacitance. They are usually made of a dielectric material such as polypropylene, polyester or polycarbonate, though some are constructed using other polymers or ceramic dielectrics. Film capacitors are typically used for bypassing, energy storage, filtering and in many applications where exceptionally stable, low current leakage and high stability are required such as audio circuits, power supplies and transistors.

The 473PSB202K2H film capacitor is a radial, non-polarized component specifically designed for applications requiring high stability and reliability. It features extended voltage, high temperature and wide temperature range rating and offers excellent electrical characteristics such as low leakage current, high stability over life and a long-term reliability. It also has a rated temperature range from -55°C to +155°C and a capacitance range of 0.0022 uF to 1.8 mF.

In terms of application fields, the 473PSB202K2H film capacitor is suitable for use in power supply circuitry, in noise suppression/low pass filter applications, voltage peak wave ripple elimination, and snubber and DC-link filter circuitry. It is also suitable for applications requiring high reliability, such as automotive, military, space, and telecom.

The 473PSB202K2H film capacitor works based on capacitance, which is the capacity of a system to store an electric charge. The capacitor is able to do so due to the presence of two layers of conducting material separated by an insulating layer. When electric charge is applied to the capacitor, the two conducting layers become charged, and that creates an electrical field in between the two layers and enables the capacitor to store energy. The amount of energy stored is proportional to the capacitance of the capacitor, which is determined by the material and the thickness of the insulating layer between the two conducting layers.

Overall, the 473PSB202K2H film capacitor is a highly reliable component offering excellent electrical performance and temperature stability, making it suitable for various applications such as power supply, filter, snubber and DC-link filter circuitry. It is also capable of functioning in a wide range of voltage and temperature ranges.
