Film capacitors, also known as plastic film capacitors, are a type of capacitor that utilizes organic film as a dielectric medium and uses thin metallic sputtered, evaporated, or metallized film as electrodes. The R474I222050A1K is one type of film capacitor, which is a general-purpose capacitor developed using polypropylene material.

The R474I222050A1K series of film capacitors are designed for applications including signal coupling, power supply bypass, power supply timing, filter, DC link in static switch, filter in electronic ballast for lighting, and other general-purpose AC signal applications. It can also be used in the manufacture of switching power supplies, motor control, inverters, solar inverters, and chargers, telecommunications, audio and high-fidelity equipment.

The working principle of the R474I222050A1K is based on the concept that two conductive plates separated by a dielectric generate a static electric charge. In the case of the R474I222050A1K, the two plates are made from thin metallic sputtered, evaporated, or metallized film, and the dielectric is an organic film made from polypropylene. For these applications, the R474I222050A1K also utilizes a layer of very thin aluminum oxide for improved insulation properties.

The R474I222050A1K is designed to offer a high-performance solution for AC signal filtering and power supply bypass, which is one of the primary applications for film capacitors. The capacitor has a high ripple current rating, which is important for filtering applications, as well as a low temperature coefficient and low dielectric dissipation factor. The operating temperature range of the capacitor is -40°C to +85°C, making it suitable for a variety of applications.

The R474I222050A1K also uses a wire-wound construction, which helps to reduce the size of the capacitor while still offering excellent performance and reliability. The low-profile design also allows the capacitor to fit into a variety of applications where space is a concern. Overall, the R474I222050A1K is an excellent choice for utilities, commercial, and industrial applications requiring a reliable and high-performance AC signal filtering and/or power supply bypass solution.
