Film capacitors, sometimes known as plastic film capacitors, are virtually non-polarized capacitors and are generally the preferred choice when stability and reliability are of the utmost importance. Typical applications include, but are not limited to, motor starting, power factor correction, and energy storage. The DME2P22K-F is a great example of a film capacitor and is a popular choice in the industry due to its excellent performance.

The DME2P22K-F is a polypropylene-film/metallized-foil capacitors which is suitable for high reliability power electronics applications. Unlike traditional electrolytic capacitors, the DME2P22K-F can deliver stability and reliability under a wide range of environmental conditions, from low-temperature cold climates to extreme heat and high-humidity. It is designed for superior failure rate performance and long service life. Thanks to its robust construction and wide-range of features, the DME2P22K-F is becoming increasingly popular for applications ranging from motor starting, power factor correction, harmonic filters, and even energy storage.

The DME2P22K-F also offers excellent operational performance with low impedance and low ESR, along with superior temperature stability with exceptionally low drift. With ratings of up to 2.2 kWh and a maximum operating temperature of 110° C, the DME2P22K-F is well-suited to meet the demands of a wide range of commercial and industrial applications. The case size of the DME2P22K-F is extremely small, giving engineers plenty of design flexibility for tight spaces and low-profile applications.

The working principle for the DME2P22K-F incorporated in a film capacitor is the alternating movement of charge carriers from the area of higher potential to the area of lower potential wherein there is a finite amount of energy storage. The dielectric material used in this case is a plastic film and the electrodes are perforated metal plates. The metal plates are placed on either side of the plastic film and a charge is applied to the two plates that creates an electrostatic field. The plastic film works as a membrane and acts as an insulator between the two metal plates, thereby interrupting their electrical conductivity. When a voltage is applied to the two metal plates, the plastic film generates an electrical field and thereby a storage capacity. This storage of charge is what we refer to as dielectric capacity or the capacitance of the film capacitor.

The DME2P22K-F offers a reliable and stable experience compared to traditional electrolytic capacitors. The DME2P22K-F capacitor has several advantages over traditional electrolytic capacitors: better temperature stability, no electrolyte leakage, higher ripple current capabilities, longer service life, and high working voltage. As a result, film capacitors like the DME2P22K-F are becoming increasingly popular across many electrical application fields such as motor starting, power factor correction, harmonic filters, and energy storage. With its top-notch features and robust construction, the DME2P22K-F is sure to remain as a trusted and reliable option for many years to come.
