Film capacitors, also known as plastic film capacitors, plastic film dielectric capacitors, or film dielectric capacitors, are a particular type of capacitor widely used in electronics. One of the most common models is the MKP385220250JII2B0. This article aims to explain the application field of the device as well as its working principle.

Application Field

The MKP385220250JII2B0 is designed for use in a variety of electrical applications, such as noise suppression, decoupling, bypass, and timing circuits. It is commonly used in high-frequency noise suppression, especially in the low-voltage and high-current wide-voltage range or long-term large-capacity ripple current environments. It is normally used in combination with filter networks, EMI filters, and RFI suppression circuits.

The MKP385220250JII2B0 is also suitable for use in general electrical circuits, acting as a buffer between circuit nodes such as power supply and load points. This function is especially important with large DC circuit boards or power flow control circuits. The device can also be used to act as a capacitor bank, which helps to smooth out power supply and reduce high-frequency noise.

Generally speaking, the MKP385220250JII2B0 is well-suited to many applications requiring a robust and reliable plastic film capacitor. Its long life, good frequency characteristics, and low temperature coefficient make it an ideal choice for use in a variety of applications.

Working Principle

The MKP385220250JII2B0 is a polypropylene film capacitor. This type of capacitor is constructed from two sheets of polypropylene plastic film separated by an electrically insulating layer. The two sides of the capacitor are connected to the electrical power source through two metal end-plates. An electric current is then passed through the device, creating an electric field between the two plates.

The electric field directs electrons to travel through the insulation layer, thus charging the capacitor. The electrons are then attracted to the opposite end plate, creating a static electric potential between the plates. This potential can store energy which can be released when the voltage across the capacitor is reversed. This is how the device functions as a capacitor.

The MKP385220250JII2B0 is a motor-run type of film capacitor, meaning that it is designed to be driven by a motor. These motors cause the capacitor to be subjected to cyclic electric fields as the motor turns. The capacitor absorbs and releases charge in response to the electric fields, allowing for efficient transfer of energy.

Conclusion

The MKP385220250JII2B0 is a widely used pelicans film capacitor. It can be used in a variety of applications including noise suppression, decoupling, bypass, and timing circuits. It is generally used in combination with filter networks, EMI filters, and RFI suppression circuits. The device is constructed from two sheets of polypropylene plastic film separated by an electrically insulating layer and is driven by an AC motor. The capacitor absorbs and releases charge in response to the electric fields, allowing for efficient transfer of energy.
