Film Capacitors

Film capacitors are kind of capacitors from the family of dielectric capacitors. It is usually made of very thin plastic films. Capacitance is created by layering of those plastic films by using special technology. This makes it good for application in a wide range of temperature conditions and for different values of capacitance. It is believed that flexible film capacitors are one of the most reliable and robust capacitors in the market today. Capacitors of this type are used in DC filtering, AC motor control, power supplies, and other general purpose applications.

930C2W2K-F Application Field and Working Principle

The 930C2W2K-F is a type of flexible film capacitor with polyester (or generally known as Mylar) as its dielectric. This makes it suitable for (DC) filtering application, especially for pi-filter and DC-link capacitor applications. The main purpose of 930C2W2K-F is to filter the residual ripple present after the rectification of power electronic circuits in order to provide sufficient quality power for the downstream circuits. The impedance characteristic and wide range of operating temperatures of the 930C2W2K-F make it suitable for use in high-temperature applications such as welding equipment and vaporizers.

The basic working principle of a 930C2W2K-F capacitor is quite straightforward and similar to other types of capacitors. The capacitor contains two metallic plates separated by a dielectric material – the ferro-electric polymer in this case. When a voltage is applied across the capacitor, an electric field is generated between the plates. This field causes the electrons in the plates to be attracted or repelled depending on the voltage applied. This generates a build-up or depletion of electrons that stores energy and creates a potential difference between the plates. This energy stored in the capacitor is then released when the capacitor is discharged.

Despite being a quite simple concept, the 930C2W2K-F also has quite unique features that make it a reliable and robust product. This includes a low ESR (equivalent series resistance) that allows very high ripple currents and highly reliable safety features. It also offers high capacitance values that can be used in higher power applications, which make it suitable for a wide range of applications.
