Film capacitors, also referred to as plastic film capacitors, are electronic components that store and release electrical energy in electronic and electrical circuits. They are usually made of thin, plastic films coated with metalized electrodes. Common materials used for film capacitors are polyphenylene sulfide (PPS), polypropylene (PP) and polyester. The R76PR41004030J is an example of a film capacitor that has a wide range of uses in the electronics industry.

R76PR41004030J Application Field

R76PR41004030J film capacitors can be used in a variety of applications including automobiles, medical devices, industrial machinery, computer peripheral, audio and broadcast systems, and telecom equipment. Their low ESR (equivalent series resistance) and high capacitance values make them ideal for high frequency filtering. They can also be used in switching regulators, high voltage DC-DC converters and voltage transformers. Because of their small size, they are also suitable for creating tiny footprints in high-density circuit boards.

R76PR41004030J Working Principle

Film capacitors use a thin layer of dielectric material (the plastic film) as an insulator between two metal layers (the metal electrodes). Electric field acts between the two electrodes and increases or decreases the capacitance depending on the applied voltage. When a voltage is applied to the capacitor, the electric field repels electrons and makes them flow to the opposite electrode, producing a current. This current is stored within the dielectric material as electrical energy and is released when the voltage is removed.

The R76PR41004030J film capacitor has a capacitance range of 0.1 uF - 0.22 uF and a voltage rating of 4V - 200V. Its small size and low ESR make it well suited for high frequency filtering applications. The temperature characteristics of film capacitors make them suitable for operation over a wide temperature range. The capacitance stability of the R76PR41004030J is rated for +10%, -20%. This means that the capacitance will remain in the specified range for a given temperature range and rated voltage.

Conclusion

R76PR41004030J film capacitors are a popular choice for a variety of applications in the electronics industry. Their wide capacitance range, low ESR and high temperature characteristics make them well suited for high frequency filtering applications in automobiles, medical devices, industrial machinery, computer peripheral, audio and broadcast systems, and telecom equipment. Understanding the application field and working principle of the R76PR41004030J film capacitor can help engineers design efficient and reliable electronic circuits.
