The capacitors feature high ripple current capability, high temperature stability, and low equivalent series resistance (ESR). They are most commonly used in switching power supplies, high-frequency circuits, energy storage systems, smartphone battery charging applications, telecommunications equipment, lighting ballasts, and many other applications. R76QN31004030J film capacitors are also frequently used in filter circuits, such as low-pass filter and high-pass filter, as well as in various active systems.

Working Principle

The working principle behind the R76QN31004030J film capacitor is similar to that of other types of capacitors. Two conductive plates are separated by an insulating barrier, with the capacitance of the capacitor being determined by the size of the plates and the material of the insulator. The capacitance of the capacitor itself is determined by the equation C = A x epsilon/d, where A is the area of each of the plates, epsilon is the dielectric constant of the insulator, and d is the distance between the plates.

R76QN31004030J capacitors are composed of a metal-film dielectric, which is a type of plastic film that features high strength, excellent dielectric characteristics, and superior temperature stability. When the capacitor is charged and discharged, the charge is stored in the dielectric material, allowing the capacitor to store electrical energy.
