Film capacitors (also known as plastic film capacitors) are high-performance capacitors that use a film as the dielectric medium. They are used for a wide range of applications in both consumer electronics and industrial products. The MKP1845447404 is a polymer film capacitor that is designed for use in a variety of electronic applications.

Applications

The MKP1845447404 is a medium-to-high voltage capacitor. It is commonly used in power factor correction applications, such as in power inverters, Uninterruptible Power Supplies, and switching power supplies. This capacitor is also used in motor drives, HVAC systems, and home appliances. In addition, it is often used in power line noise suppression applications, such as the suppression of EMI/RFI (electromagnetic interference/radio frequency interference).

The MKP1845447404 has a variety of characteristics that make it suitable for various applications, including: low equivalent series resistance (ESR), low inductance, small size, and long electrical life. It is also designed to provide protection against short circuits, overvoltage, and over-temperature conditions.

Working Principle

Film capacitors are polarized, meaning they must be connected properly to ensure the correct operation of the circuit. The MKP1845447404 has an aluminum back-plate which is the anode, and the electrode is the cathode. When the capacitor is connected with reverse polarity, the voltage across the device will exceed its rated voltage, and can cause it to fail.

The MKP1845447404 utilizes a film dielectric, and has two metal plates separated by the film. When a current is applied to the metal plates, an electrostatic field is created between them, which stores the electrical charge. When this electrical charge is removed, the electrostatic field is also decreased, therefore releasing the stored energy.

The MKP1845447404 is designed to have a low equivalent series resistance (ESR), which is important for providing high current operation capabilities. The ESR is a measure of the losses that occur confined within a capacitor, and is a combination of resistance and inductive reactance. The lower the ESR value, the less energy is lost in the process.

Conclusion

The MKP1845447404 is a polymeric film capacitor that is designed for a variety of application, including: power factor correction, power line noise suppression, motor drives, HVAC systems, and home appliances. The capacitor utilizes a film dielectric, and has two metal plates separated by the dielectric, which exhibits a low equivalent series resistance (ESR). The MKP1845447404 is designed for medium-to-high voltage applications and is suitable for high current operation with minimal losses.
