Film Capacitors

Film capacitors are compact, high-performance capacitors made of a thin film of polyester or polypropylene dielectric material. They offer low equivalent series resistance (ESR), low temperature characteristics, excellent linearity, low loss, excellent frequency characteristics and superior insulation performance. Commonly used film capacitors include polypropylene and polyester film capacitors, metallized polypropylene capacitors, and paper capacitors.

MKP385347160JII2B0 Application Field and Working Principle

MKP385347160JII2B0 is a type of metalized polypropylene film capacitors designed for AC and low DC voltage application. These capacitors provide excellent performance for AC filtering, DC link capacitors, AC noise smoothing, power factor correction, motor starting, and power supplies. The main advantage of this type of capacitor is their low leakage current, low dissipation factor, and low inductance. This makes them ideal for power applications such as UPS, inverters, motor control, and so on.

The working principle behind MKP385347160JII2B0 is the combination of the material used in its construction and the special metalized polypropylene film. The metalized polypropylene film is composed of a layer of semiconductor electrode material. This creates an electrical barrier that prevents the electrons from crossing the film and reduces the leakage current. The capacitor’s dielectric material is a foam made of polyester and composed of tiny air bubbles. These tiny air bubbles create an insulation layer that reduces the dissipation factor and increases the dielectric strength of the capacitor.

The capacitor consists of two electrodes, which are then separated by the dielectric material. The electrodes are transparent, allowing electrons to pass freely from one electrode to the other. This electrical transportation creates an electric charge, which is stored in the capacitor. The capacitance of the capacitor is proportional to the area of the electrodes and the thickness of the dielectric. The dielectric strength of the capacitors is high, making them suitable for high voltage applications.

MKP385347160JII2B0 capacitors are also designed for pulse noise and signal filtering. They are commonly used in audio/video equipment, lighting systems, electronic toys, and other consumer electronic products. They can also be used in power factor correction and voltage stabilization. These capacitors have a wide temperature range for operation (from -55°C to +125°C).

In conclusion, MKP385347160JII2B0 is an ideal type of film capacitors for AC and low DC voltage applications. The use of metalized polypropylene film and special foam polyester dielectrics provides excellent performance for AC filtering, DC link capacitors, AC noise smoothing, power factor correction, motor starting, and power supplies. It also offers excellent temperature characteristics, low inductance, and low dissipation factor for pulse noise and signal filtering applications.
