Film Capacitors

Film capacitors, also known as polyester capacitors, are one of the most widely used types of capacitors in the world. The main body of them consists of a thin dielectric film, usually polyester film, and two metal layers. The capacitance value of a film capacitor largely depends on the thickness and surface area of the dielectric film. Compared to other types of capacitors, film capacitors feature a wide range of capacitance values, higher capacitance stability, long life expectancy, and excellent insulation capability.

An SCRN239R film capacitor is a specific type of film capacitor. It is a radial leaded non-polarized type with high-temperature and high-flexibility ratings. With a capacitance range of 0.047μF and voltage rating of 1500VAC, an SCRN239R film capacitor is suitable for a wide range of applications, such as motor drives, industrial lighting, and high-power audio.

The working principle of an SCRN239R film capacitor is based on electrostatic field. When two metal leads connected to the capacitor plates of its housing are applied with a voltage, it develops an electric field between the two metal layers. The produced electric field generates an electric charge between the two metal plates, and an electric current is established across them. Thus, an electric current can flow through the capacitor.

The SCRN239R film capacitor has excellent characteristics for high-voltage environments. It provides high voltage rating of 1500VAC, high insulation resistance, and excellent capacitance stability of 0.2% over a wide temperature range of -40℃ to +105℃. The SCRN239R film capacitor is suitable for many applications that require high reliability and stability.

In conclusion, an SCRN239R film capacitor is a type of film capacitor with high-temperature and high-flexibility ratings. It is suitable for a wide range of applications such as motor drives, industrial lighting, and high-power audio. The working principle of an SCRN239R film capacitor is based on electrostatic field that produces an electric charge between two metal plates when a voltage is applied, and an electric current flows through the capacitor. It provides excellent characteristics for high-voltage conditions and features a high voltage rating, high insulation resistance, and excellent capacitance stability.
