R75LI33304000K Working Principle

R75LI33304000K is a metallized polypropylene film capacitor. It is constructed of two metallic electrodes deposited opposite each other on the polypropylene film. Its design makes them particularly low in impedance and dielectric loss. The two metallic electrodes act as plates separated by the dielectric material, forming the capacitor. This creates an environment where electric charge can build up on the plates.

When an external electric charge is applied, it causes a variation of the electrical field between the plates. This causes a build up of electric charges on each of the plates. The charge is prevented from flowing by the dielectric between the plates. This creates an electric potential between the two plates, which is referred to as the capacitance. The capacitance of the R75LI33304000K is 33,000pF.

Under normal operating conditions, the dielectric material has very low losses and therefore the capacitance of the R75LI33304000K remains largely constant. The voltage rating for this type of capacitor is up to 400V. This makes it suitable for applications requiring high-precision and stability.

Conclusion

The R75LI33304000K metallized polypropylene film capacitor is a type of film capacitors, that offers a wide range of applications. Its main advantages are its small size, low ESR, and high temperature stability. It is suitable for high end audio systems and power electronics, as well as DC/DC converters and EMI protection. Its working principle is based on two metallic electrodes along with a dielectric material in order to create a potential difference between the plates. It has a capacitance of 33,000pF and a voltage rating of up to 400V.
