Film capacitors are widely used components in electronic equipment due to their excellent electrical properties, small size, and low cost. The MKP385539063JPI4T0 is a type of high temperature polypropylene film capacitor with an operating temperature range of -40°C to +125°C. These capacitors are usually used in amplifier circuits, shunt regulators, DC-DC converters, high stability filter circuits, phase shifting, and voltage controlled circuits.

Polypropylene capacitors are often used in audio-video applications, due to their excellent audio frequency performance, low distortion, and excellent linearity even when exposed to high temperature and high-frequency noise. MKP385539063JPI4T0 film capacitors have a dielectric system that provides high insulation resistivity and excellent temperature characteristics. They can be used in power supplies, loudspeakers, and for signal bypassing.

The MKP385539063JPI4T0 is constructed by first forming polypropylene film into thin layers, then winding it into a cylindrical shape with very precise spacing between each layer. The winding is then wrapped with a metalized foil shield and a protective outer coating to protect against humidity, dust, and other environmental factors. These capacitors are designed to have a self-healing process, where any short circuits between the layers are automatically restored.

The MKP385539063JPI4T0 film capacitor offers low equivalent series resistance (ESR) and low inductance, making it ideal for applications with high AC ripple currents, low impedance, and transient response. It also features low dissipation factor and high insulation resistance, resulting in superior performance and reliability over many other types of capacitors. The high current capacity and low voltage coefficient make the MKP385539063JPI4T0 suitable for applications with high dynamic loads.

The working principle of film capacitors is based on the fact that two layers of dielectric material, such as polypropylene in this case, store electric energy when a voltage is applied. The voltage is then stored in the form of an electrical field between the two layers. When the voltage is removed, the stored energy is released and the capacitor can be used again. The stored energy is proportional to the applied voltage and the area of the two layers, and is subject to several electrical parameters, such as dielectric constant and dissipation factor.

The MKP385539063JPI4T0 film capacitor is an excellent choice for applications with high frequency, high current, and/or high temperature requirements. Its excellent electrical characteristics make it ideal for a variety of uses, such as bypass capacitor, smoothing capacitor, and output capacitor for low voltage circuits. It is also suitable for use in switching power supply circuits, audio-video applications, and instrumentation circuits.
