Film Capacitors

Film capacitors are used in various applications where excellent electrical performance is required. They are composed of thin films of plastic insulation, usually mylar, which are treated to a very thin, high-performance electrode able to quickly absorb and discharge energy. The uniformity of the films, combined with the capacity of the dielectric material, is critical for determining the performance of the capacitors. Depending on the application, capacitors may be filled completely with a dielectric material, partially filled, treated with a special coating layer or sealed in a vacuum.

C44UQGQ6500F8SK application field and working principle

The C44UQGQ6500F8SK is a film capacitor used mainly in signal filtering and signal rectification applications. It is suitable for DC and AC applications below 500V with a current of up to 15A. It is temperature stabilized and hermetically sealed, making it ideal for use in harsh environments. The C44UQGQ6500F8SK uses a dual layer of mylar films that have been vacuum-sealed with a special coating layer. This coating layer allows the capacitors to quickly switch from storing to releasing energy that makes it a suitable choice for applications such as power factor correction and AC line-start capacitors. Other uses include high-power industrial controllers, audio amplifiers, and DC-DC converters.

Working Principle

The C44UQGQ6500F8SK film capacitor works by allowing currents to pass between two electrodes separated by an insulating layer, often in the form of plastic films. When an AC current is applied, the capacitance of the device increases, allowing a greater amount of current to flow than with a non-capacitive device. The insulating material between the two electrodes limits the amount of current that can pass through and hence, the voltage that can be stored. The maximum and minimum voltages that can be stored depend upon the capacitance of the device, which is determined by the size and area of the electrodes.

In addition to its capacity to store energy, the C44UQGQ6500F8SK film capacitor also acts as a low-pass filter by blocking high-frequency noise. This phenomenon is known as self-gate, where the device acts as a barrier and prevents the passage of higher frequency signals but allows lower frequency signals through. This makes the device suitable for applications that require filtering of high-frequency noise, such as in communications, power supplies, and automotive electronics.

The C44UQGQ6500F8SK film capacitor is an excellent choice for applications requiring high reliability and performance in harsh environments. Its ability to quickly absorb and discharge energy paired with its low-pass filtering capabilities make it ideal for use in a variety of applications.
