Working Principle

The 715P47256JA3 film capacitor is an electrochemical device composed of two layers of plastic films. The conducting dielectric film is typically made from polyester and has a high dielectric constant. The capacitance of the device is determined by the area of the dielectric film and the distance between the two electrodes. The dielectric film is then laminated between two metal or aluminum plates which form the electrodes.

The capacitance of a film capacitor is greatly affected by its construction, temperature, and environment. As such, the capacitance will vary depending on how the capacitor is used in a given application. In general, a film capacitor will exhibit higher capacitance values when exposed to high temperature and low humidity. On the other hand, high humidity with low temperature will generally decrease the device\'s capacitance.

The 715P47256JA3 film capacitor has excellent electrical characteristics, including a high dielectric absorption ratio, low leakage current, and a low ESR rating. These features make it a suitable choice for applications that require high capacitance values in a small footprint. In addition, it has an extremely low self-discharge rate, making it a reliable solution for critical applications, such as automotive, aerospace, and military systems.

The 715P47256JA3 film capacitor is an invaluable component for a wide range of industrial and consumer applications. Its small size, high capacitance, and excellent electrical characteristics make it an excellent choice for a variety of applications, from audio equipment to automotive systems.
