R75II38204080J Film Capacitor Application Fields and Working Principles

Film capacitors, also known as polyester capacitors, are non-polarized capacitors with a plastic film as the dielectric. The R75II38204080J Film Capacitor is a type of film capacitor manufactured by the Japanese company Rubycon Corporation. This capacitor is a metalized polyester film capacitor with a radial plastic case.

Application Fields of R75II38204080J Film Capacitor

R75II38204080J film capacitors are widely used in power supplies, motor drives, lighting control applications, telecommunications, and other industrial applications. These film capacitors are generally used for bypassing, clamping, buffering and filtering. They can also be used in audio circuits, such as high-end amplifiers and receivers, for high-frequency noise suppression.

Working Principle of R75II38204080J Film Capacitor

Film capacitors work on the principle of electrostatic capacitance. In any capacitor, two electrical conductors (plates) are separated by a dielectric material (insulator). A voltage applied across the two plates will create an electric field within the dielectric material, which stores the energy. The amount of energy stored in the capacitor is related to the capacitance or ability of the capacitor to store charge. The R75II38204080J film capacitor uses a thin plastic film as a dielectric, which is then metallized on both sides with unique electrode materials, and encased in a plastic body. This type of film capacitor offers several advantages, such as a high capacitance value, a compact size, and a low ESR (equivalent series resistance). These film capacitors have low capacitance tolerances that range from ±10% to ±20%. The R75II38204080J film capacitor has a capacitance of 0.82uF, a voltage rating of 50V, and an operating temperature range of -55°C to +105°C. It has a low ESR of 1.7 ohms and is RoHS compliant.

Conclusion

R75II38204080J film capacitors are widely used in many applications due to their high capacitance value, low ESR, and excellent temperature performance. They are simple to use and have a wide tolerance, with ±10% to ±20% being the standard. They are reliable and efficient, making them an ideal choice for a variety of applications.
