Film capacitors, also known as metallized plastic film capacitors or plastic film capacitors, are capacitors that use thin plastic films as the dielectric material. They are constructed of either metallized dielectric layers, sandwiched between metal electrodes or plastic film dielectric layers with metal or carbon electrodes. The MKP385227160JDA2B0 line of film capacitors are made from a polypropylene (PP) dielectric film with metalized electrodes, specifically designed for applications such as filter, bypass, signal coupling, snubber and surge-protection.

In terms of size, the MKP385227160JDA2B0 capacitors measure in at 8x8mm, with a capacitance range of 160pF to 2200pF, and an outside diameter of 20mm. Rated voltage range is 600Vac and capability to handle up to 2000Vac of working voltage. Their rated dissipation factor (Df) is a very low 0.08% at 1kHz and a high insulation resistance of more than 100G ohms at 1kHz, 25°C. The MKP385227160JDA2B0 series are 65/85/105°C rated temperature range, compliant with EN-safety standards and have a self-healing mechanism, making them extremely reliable in all kinds of environments.

The working principle of the MKP385227160JDA2B0 capacitors is based on the Faraday\'s Law of Electromagnetic Induction. When the film capacitor receives an alternating current, the electric field rises around the wire windings in the capacitor. This creates a dielectric field strength which is equal to the applied voltage. The dielectric field strength is proportional to the capacitance and inverse to the dielectric constant of the material. This causes polarization of the dielectric material which creates a negative charge on one side of the film capacitor and a positive charges on the other side.

This electric field attracts electrons from the one side which move across the dielectric and create an electric field with the same strength on the other side. This electric field then attracts electrons and thus a current path is created through the capacitor. This current path facilitates the transmission of the alternating current.

The MKP385227160JDA2B0 film capacitors are widely used in industrial automation, medical equipment, HVAC systems, instrumentation, LED lighting, power tools and renewable energy systems. Their self-healing mechanism, a low-Df value, extremely low leakage currents and a rated temperature of 65/85/105°C make them an ideal choice for low noise signal processing applications like high-end audio and video systems. In the automotive industry, these type of capacitors are also used due to their high reliability and long-term stability.

The applications of the MKP385227160JDA2B0 film capacitors are limited only by their size and the maximum voltage they can handle. Their design and size make them easy to install and they are approved for many European safety standards (X2-marked) which also increases their popularity for Europe-based applications.
