Film Capacitors

A film capacitor is an electronic component made out of a thin dielectric film. It functions in the same way as a traditional dielectric capacitor, but is shaped differently and has a relatively high insulation value. Film capacitors are known for their high frequency response, low leakage rates, and high capacitance, making them a popular choice for power supply applications. In addition, the thin film construction makes them extremely sensitive to variations in temperature, making their use in temperature control circuits essential.

MKP385418016JCM2B0 application field and working principle

The MKP385418016JCM2B0 is a motor start film capacitor and is widely used in AC motors, compressors, pumps and gear motors. The most common application is starting and running AC motor with a single phase supply, as it helps to reduce the start-up current. The capacitor has a high-temperature stability of up to 85°C and is rated to withstand -40°C to +85°C ambient temperatures. The MKP385418016JCM2B0 is constructed of polypropylene film, has a capacitance of 50µF and a voltage rating of 400V.

The working principle of the capacitor is that it stores a charge and by doing so, creates an electric potential between its two plates. This potential energy is used in applications to provide a boost of energy when needed, such as when an AC motor is starting. When the capacitor is connected to a motor, the electric potential will start to decrease as the motor draws energy from the capacitor. Once the energy stored in the capacitor is fully depleted, the motor will keep running as it draws power from the power supply.

Film capacitors, such as the MKP385418016JCM2B0, are commonly used in many AC electric motor applications as they provide the necessary current and voltage for the motor to operate. They are also preferred due to their high-temperature resistance, high capacitance, and wide capacitance range, making them well suited for a variety of motor applications.
