Film Capacitors

Film capacitors are a type of energy storage device commonly used in electrical and electronic circuits. They are made of thin layers of conducting material separated by insulating material, usually a thin plastic, paper or ceramic film. The thin layers are typically rectangular and the resulting structure is known as a parallel plate capacitor.

The MKP1841312406G is a specific film capacitor manufactured by Murata. It is a polyester film capacitor commonly used in AC applications and is designed to provide good capacitance stability and long life. The MKP1841312406G features a rated voltage of 250VAC and is suitable for use in high-power pulsed applications.

Application Fields

The MKP1841312406G is most commonly used in high-frequency power supplies, switching power supplies, DC-DC converters, uninterruptible power supplies and high-power inverters. It is also suitable for use in motor drives, audio amplifiers and digital audio equipment. Due to its low ESR and high dV/dt characteristics, the MKP1841312406G is well-suited to applications with fast transient conditions where high power dissipation is expected.

Working Principle

The MKP1841312406G capacitor works by providing a short circuit between a pair of electrodes. The capacitor is filled with an insulating material, which is designed to provide a high working voltage. The two plates of the capacitor are connected to each other via a dielectric medium, such as a paper or a dielectric film. The voltage applied to the capacitor polarizes the dielectric medium, resulting in a build up of charge on the plates. As current flow through the dielectric, electrons are attracted to the positively charged plate and repelled by the negatively charged plate. This creates an electric field between the two plates, which stores energy that can be released when the capacitor is disconnected from the circuit.

The MKP1841312406G is designed to handle high-power pulsed applications and features a long life due to its high insulation resistance and low leakage current. The high insulation resistance also helps to ensure a stable capacitance over time, while the low leakage current helps to reduce power losses and avoids interference in electronic circuits.

Conclusion

The MKP1841312406G is a polyester film capacitor designed for use in AC applications requiring good capacitance stability and long life. It is suitable for use in high-frequency power supplies, switching power supplies, DC-DC converters and uninterruptible power supplies. The capacitor is designed to handle high-power pulsed applications, with a rated voltage of 250VAC. The capacitor has a high insulation resistance and low leakage current, ensuring that it has excellent reliability and a long life.
