Film Capacitors

Film capacitors, also known as plastic film capacitors, or simply film caps, are an important class of parallel-plate capacitors. They are mostly made from plastic films as its dielectric layer, with a couple options of metalized films or ceramic substrate as other choices. The most common configurations are insulated or non-insulated, single layer or stacked, self-healing or nonhealing.

MKP1837347164G Application Field and Working Principle

MKP1837347164G is a film capacitors developed by us for a wide range of applications that require power electronic systems. This capacitor is appropriate for the applications with high voltage, low ESR requirement, and wide frequency band switching power supply. It is also widely used in solar farms, industrial motors, aircraft engines, automobile power systems, medical equipment, and other fields.

The working principle of this film capacitors is based on the classic capacitor theory. By the dielectric layer in between two metal plates, an electromagnetic field is established, and thus, electric charge is stored, leading to the storage of energy.

The dielectric layer used in MKP1837347164G consists of Polypropylene Film (PPF) capable of achieving ultra-low losses and low ESR value. Developed with advanced stacking/interleaving technology, this film capacitors can provide a much higher operating voltage while still maintaining a low ESR and high energy storage.

Besides, this MKP1837347164G film capacitors is also equipped with a unique self-healing feature. Even if the PPF films are broken, the capacitor will continue working correctly as it will automatically discharge any surface charge.

In terms of the electrical characteristics, the capacitance of this film capacitors is usually 0.1~1000uF, the voltage is 400V/630V DC, and the ambient temperature range is -40~85 degrees Celsius. As for other technological parameters like frequency response, ESR, and maximum ripple current, we can also provide customized features.

To conclude, the MKP1837347164G film capacitors is a reliable and versatile device that can fit various fields powering requirements. Its low ESR value and advanced self-healing feature make it ideal for wide frequency range switching power supply.
