Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor which utilizes a plastic film as the dielectric as opposed to ceramic or metal oxides. The term \'film capacitor\' is most commonly used in the industrial and electronic engineering communities, as it can refer to many different types of capacitors.

MKP385356085JFI2B0 application field and working principle

The MKP385356085JFI2B0 is a type of film capacitor which is commonly used in applications such as audio crossover networks, dc blocking, harmonic filters and other applications which require an overall small form factor with low impedance characteristics. The capacitor utilizes a polypropylene film dielectric, which is then coated with an alumina layer. This layer increases the dielectric constant of the capacitor, allowing for a much higher capacitance than would be possible with a polypropylene film alone.

The working principle of the MKP385356085JFI2B0 is quite simple; the capacitor is composed of two highly conductive metal plates, which are separated by a thin insulating layer. When an electric current is applied, a voltage difference is created between the two plates, which creates an electric field within the dielectric layer. This electric field is capable of storing energy, and thus can act as a capacitor.

The MKP385356085JFI2B0 has a variety of benefits that make it ideal for use in many different applications. First, the low impedance characteristics make it well-suited for power supply filtering, as it can handle a wide range of frequencies with low distortion. Secondly, the small form factor allows for easy integration into existing designs. Lastly, the polypropylene film dielectric offers better temperature resistance and durability than many other types of capacitors.

In conclusion, the MKP385356085JFI2B0 is an excellent choice for applications which require a small form factor, low impedance characteristics, and temperature resistance. The capacitor utilizes a polypropylene film dielectric, which is then coated with an alumina layer, allowing for a high capacitance while still providing good temperature resistance. This makes it ideal for use in audio crossover networks, dc blocking, harmonic filters, and other applications which require a small, low-impedance capacitor.
