Film capacitors are widely used in a variety of applications. The R474I268050A2K is an example of a film capacitor designed for high-frequency applications. It has a high level of reliability and offers good performance stability and low ESR.

A film capacitor consists of two metal plates separated by a plastic film isolated between them. The plastic film has a high dielectric constant and is a good insulator. This allows the capacitor to store and release energy more efficiently than standard capacitors. The capacitance and working voltage of a film capacitor can be adjusted by selecting the right film material and the geometry of the plates.

The R474I268050A2K is a standard size film capacitor with a rated voltage of 50 volts. It has a tolerance of ±5% and a noise level of 0.2μV. It has a low ESR of 0.05 Ohms and a capacitance range from 0.5 to 10,000 μF. It offers good performance stability and superb ripple current capability. Its wide temperature range of -55 to +125°C makes it suitable for applications in extreme environmental conditions.

The working principle of a film capacitor is relatively simple. When a DC voltage is applied to the two plates, a dielectric field is created which separates the plates and stores energy in the dielectric. When a current is released through the capacitor, the stored energy is released and the plates are discharged. The amount of energy a capacitor can store is proportional to its capacitance, which is determined by the type of film material and the distance between the plates.

The R474I268050A2K film capacitor is ideal for use in high-frequency applications, such as resonant coils, filters, and tracking circuits. Its low ESR and high ripple current capability are particularly advantageous for pulse applications. Its wide temperature range also makes it suitable for applications in harsh environments.
