DME2P82K

Film Capacitors

The DME2P82K is a film capacitor designed specifically for applications in HVAC, lighting, ballasts, and power factor correction. This type of capacitor is a small, non-polarized, polypropylene film capacitor with a capacitance rating of 0.002uF. It features an environmental rating of up to 50V AC, with an operating temperature range of -40C to 70C.

Mechanical Structure of the Film Capacitor

The DME2P82K is composed of several mechanical elements, which include a polypropylene film dielectric, a metalized film layer, and a resin coating. The polypropylene film dielectric is a nonconducting polymer film, which is capable of withstanding high temperatures. The metalized film layer provides the necessary surface area to hold a charge. The resin coating is usually made up of a phenolic or epoxy compound, which acts as an insulator between the metalized film layer and the case of the capacitor. The capacitance of a capacitor is proportional to the surface area of the metalized film layer and inversely proportional to the thickness of the dielectric.

Working Principle

The DME2P82K operates by storing electrical energy in the form of electric fields between the metalized film layer and its dielectric material. This causes a voltage to be created across the capacitor, which is proportional to the capacitance rating of the device. In other words, the higher the capacitance rating, the higher the voltage. A voltage increase can then be applied to the capacitor which will cause a current to flow through it. This current will then be used to power a load connected to the capacitor.

Applications of the Film Capacitor

The DME2P82K is a compact and highly reliable capacitor, making it ideal for a variety of applications. Some of the most common applications include HVAC, lighting, ballasts, and power factor correction. The use of this capacitor helps to increase system efficiency by helping to reduce power consumption. It can also help to reduce the need for large power-consuming components, which can help to reduce system cost.

Advantages of the Film Capacitor

The DME2P82K offers many advantages including a long-life cycle, high reliability, and low power consumption. The non-polarized construction of the capacitor means it can be used for both AC and DC applications, and the wide operating temperature range of -40C to 70C allows it to be used in a wide variety of environments.
