Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor developed from various types of plastic films. They use thin, insulating plastic films as the dielectric material and a flexible metal or aluminum foil as the electrodes. They are excellent devices in electronic products due to their small size, superior volumetric efficiency, stable electrical characteristics, and low noise levels.

One type of film capacitors are the DME10P22K capacitors, which are designed for high frequency and high-temperature applications. This type of capacitors is constructed with polypropylene dielectric film, sheet metal electrodes, and a non-inductive winding. The construction ensures consistent performance and reliability even in extreme conditions. DME10P22K capacitors provide high current handling, low electrical parasitics, and a wide range of capacitance values.

Application Field

DME10P22K capacitors are used in a wide array of applications such as high frequency RF filters, immersion detectors, data converters, motor drives, lighting control, switching power supplies, and power conditioners. Due to their small size and superior performance, they are ideal for use in high-density, compact electronic circuits.

Working Principle

A film capacitor is constructed of a dielectric material sandwiched between two metal or aluminum foil electrodes. When positioned in a circuit, the metal or aluminum foil electrodes are charged with electrical energy, creating an electric field between them. The electric field creates the capacitive effect, storing electrical energy and allowing current to flow. In a DME10P22K capacitor, the dielectric material is polypropylene, which provides higher current handling and lower electrical parasitics.

The construction of the DME10P22K ensures reliable operation even in extreme conditions. The electrodes are connected in a non-inductive manner, which helps to reduce inductance and unwanted frequency components. The polypropylene dielectric provides consistent capacitor performance, high current handling, and lower electrical parasitics.
