Film Capacitors

Film capacitors are polarized capacitors with metalized plastic film sputtered onto the surface of a pre-treatedpolypropylene film. They are also known as metallized film capacitors, polypropylene capacitors, film foil capacitorsand, colloquially, as plastic capacitors. Film capacitors are available in a very wide range of values, from capacitances of a few picofarads to many tens of microfarads, with voltage ratings from a few volts up to several kilovolts.

The MKP1841420254 Capacitor is a film capacitor designed for general purpose use with a rated voltage of 275 VAC and an operating temperature rangeof -40°C to +85°C. The MKP1841420254 has low dissipation factor of 0.4% @ 1 KHz and maximum capacitance tolerance of +/-5%. The MKP1841420254 capacitor uses an industry standard radial lead design and is UL-recognized, meaning there is no special testing required for certifying its use in products.

MKP1841420254 Application Field and Working Principle

The MKP1841420254 is typically used in applications such as AC/DC motor controls, switching power supplies, power inverters,uninterruptible power supplies, high voltage pulse generators, frequency compensations, and surge suppressors.

The working principle of the MKP1841420254 film capacitor is quite simple. The capacitance of a film capacitor is determined by the size of the area of the plastic film on which the metalized layer is applied. When it has been connected across the applied voltage, an electric field exists between the two plates, causing the voltage to be divided between the metalized layers of the film. In this way, the capacitance of the capacitor is determined by the total area of the metalized layers.

TheMKP1841420254 capacitor is a non-polarized capacitance type, meaning that it is used in alternating current applications and is capable of operating in either direction. This makes the MKP1841420254 an excellent choice for applications where high power and high alternating current frequencies are involved.

The MKP1841420254 capacitor is rugged and reliable due to its metallized polypropylene film construction. This construction allows it to have a very wide temperature range, from -40°C to +85°C. The MKP1841420254 also has low leakage currents and high insulation resistance, making it suitable for high voltage applications.

Overall, due to its wide temperature range, high capacitance values, and high voltage rating, the MKP1841420254 capacitor is an excellent choice for a variety of applications. It is suitable for use in a wide range of applications including AC/DC motor controls, switching power supplies, power inverters, uninterruptible power supplies, high voltage pulse generators, frequency compensations, and surge suppressors.
