Introduction to Film Capacitors

Film capacitors, sometimes referred to as plastic film capacitors or polyester film capacitors, are a special kind of capacitor with a very thin film dielectric made of varying polymers materials. Developing from the traditional paper in oil types of capacitors, these capacitors are renowned for their excellent electrical characteristics and small form factor. Common application fields for these capacitors include AC applications, DC applications, analog circuits, digital circuits, high frequency circuits, and long term applications.

R46KN333050N0K Application Field and Working Principle

The R46KN333050N0K capacitor belongs to the family of plastic film capacitors. It is a polyester film capacitor designed primarily for DC and low AC applications. This capacitor is a ‘dry-electrolytic’ capacitor, which means that the capacitor contains no electrolyte solutions and also no cans. Its capacitance value is extremely stable and its ESR (equivalent series resistance) is low, making it a perfect choice for use in wide range of DC and low AC applications.The R46KN333050N0K capacitor is a box-type capacitor which is rated for 50V DC and 50kHz AC operations. It has a Class X dielectric with 500V, 1.3aF capacitance value at 20°C. The R46KN333050N0K capacitor operates in temperatures from −25°C to +85°C, ESR as low as 0.02 ohms and a temperature coefficient between ±100ppm/K and ±300ppm/K. It offers excellent performance in DC, AC and high frequency circuits, providing a tight tolerance of ±5% and low leakage current even in high humidity environments. The working principle of the R46KN333050N0K capacitor is based on the simple dynamic of the attraction and repulsion of electric charges that are stored between its two conductive plates. When voltage is applied to the capacitor, the current flows through it and the capacitor is discharged. When the voltage is reapplied to the capacitor, the capacitor recharges and the cycle begins again. These charge cycles allowed the capacitor to store and release electric energy, thus acting as an energy reservoir.

Conclusion

The R46KN333050N0K is a high performance plastic film capacitor suitable for a wide range of DC and low AC applications. It offers excellent electrical characteristics and small form factor, making it an ideal choice for use in high frequency, long term, AC and DC circuits.
