Film capacitors, also known as plastic film capacitors, are components made of several thin plastic films lined up with either metal electrodes, or metal plates. The most commonly used films are polyester film (PET) and polypropylene film (PP), and each of these films belong to a specific dielectric material you can think of as the insulator when a voltage is imposed across it.
WMF2W1K-F capacitors is a polyester film capacitor with ultra-low ESR, voltage rating up to 630V and capacitance range up to 2.2μF.This series is specifically designed for high frequency applications. Their rugged construction featuring enhanced single end vented housing with an epoxy filling resin can provide high performance and reliability under the most critical environment.

Application Field and Working Principle

WMF2W1K-F capacitors are mainly used in DC link circuits, for instance, frequency converters used in elevators, AC servo motor, vector motors, etc. It is also used in DC/DC converters, audio coupling filters, DC link circuits, and as a high-temporal stability filter, compared with high and low ESR types.

In terms of working principle, the current in a capacitor flows in cycles. The capacitor can be thought of as a storage tank, where an electric charge can flow from one side to the other. It can also be thought of as a light switch, where the current flows on and off, in the form of an alternation between potential positive and negative charge. Depending on the type of material used to make the capacitor, the current will flow either negatively or positively. In a film capacitor, the current will flow in the direction of the electrodes, from one side to the other.

Because the capacitor is made of metal and plastic, it is considered a dielectric material. When a voltage is imposed across the plastic film, the positive and negative charges push against each other to create a uniform electric field. This electric field allows current to flow across the film. The current is then discharged and the capacitor is then recharged. Thus, a capacitance is formed and the capacitor can store energy.

With its enhanced single end vented housing, WMF2W1K-F capacitors has a good ability to withstand high frequency voltages. In addition, its epoxy filling resin is capable of providing high performance and reliability in most critical environments, such as high temperature. It is also capable of withstanding lower temperatures and higher humidity, and have a good response to change in voltage.

Overall WMF2W1K-F capacitors is a fast and reliable solution to the DC link circuits in all the areas. It provides capacitance up to 2.2μF and a voltage rating of up to 630V. With its enhanced construction and superior features it has become an integral component for various industries.
