Film Capacitors

A film capacitor, also known as a plastic film capacitor, is a type of capacitor which uses a film as an electrolyte to store electrical energy. It has advantages of high capacitance, low distortion and low dielectric loss in the frequency range of a few kHz. They are typically used in high frequency applications, such as audio equipment, video equipment, or DC/DC converters.

The Marker Part Number (MPN) for the film capacitor is MKP385427063JC02Z0. This type of capacitor is designed for AC line filtering and as EMI/RFI suppression. It has a very low equivalent series resistance (ESR) of 0.0075 Ohms, which helps minimize voltage drops when high power is being drawn from the line.

The capacitor’s working principle is based on the principle of electrostatics. It uses a polarized dielectric material, usually a thin plastic film, that has an electric charge on its surfaces. When a voltage is applied to the capacitor, electrons are drawn to the surface of the dielectric material and a field is produced. This field stores energy, like that of a battery, and can be released when the capacitor is discharged.

Common applications of the MKP385427063JC02Z0 include the filtration of AC line voltage in motor drives and electronic equipment such as laptop computers, professional audio/video equipment, backlighting circuitry, and professional lighting fixtures. It can also be used to provide energy storage during power fluctuations.

The capacitor is designed with a mechanical envelope and electrical margins to ensure electrical safety and reliable performance. Its maximum operating temperature range is from -40°C to +105°C. Under normal operating conditions and when operated within its rated specifications, it provides reliable long-term performance and durability.
