Film capacitors are widely used for power factor correction in AC systems, such as motor control, electric welding, and harmonic filtering, due to their high-power capabilities and low ESR. The FCP0805C682G is a film capacitor fit for more specialized applications, such as high-voltage pulse applications and high frequency circuits. While film capacitors have many distinct qualities, the FCP0805C682G has some of its own, which makes it a versatile component in certain applications.

Application Field

The FCP0805C682G is best suited for the high-voltage pulse applications in various high frequency circuits. This means that it can endure and even withstand voltages as high as 1.5kV. Besides its high-voltage capability, it also offers a low equivalent series resistance (ESR), which helps filtering out harmonic currents in power supplies and generators.

In addition, the FCP0805C682G is suitable for motor control applications. Compared to other film capacitors, it has better frequency response and damping performance. This can help reduce electrical noise and interference from motor control circuits. As a result, the FCP0805C682G provides better motor control accuracy.

Finally, the FCP0805C682G is also suitable for electric welding applications due to its excellent heat resistant and high-current capabilities. It can store up to 10 times the energy of an aluminum electrolytic capacitor of the same size, making it ideal for these types of applications.

Working Principle

The FCP0805C682G is constructed from two electrodes are between a film of high-dielectric material, usually polypropylene. This type of capacitor is considered a non-polarized capacitor, meaning that the cathode and anode are interchangeable. The main advantage of such capacitors is their low ESR, meaning that they can handle higher frequencies than other types of capacitors.

When a voltage is applied to the FCP0805C682G, the field between the electrodes of the capacitor causes electrons to accumulate on the surface of each electrode. This accumulation of electrons is referred to as polarization. As the electrons become more polarized, they oppose the flow of current and the capacitor’s impedance increases. This impedance is what allows the FCP0805C682G to act as an AC filter, blocking unwanted frequencies.

In addition, the FCP0805C682G’s film also has high heat resistance, meaning that it can withstand extreme temperatures without breaking down. This makes it even more suitable for applications that may require higher voltages or more current than other types of capacitors can handle. Additionally, due to its construction, the FCP0805C682G has excellent vibration resistance, which helps reduce electrical noise.

Overall, the FCP0805C682G is an excellent choice for applications that require high-voltage pulses, high-current, and high-temperature performance. Its low ESR also makes it an ideal choice for any circuit that needs to filter out harmonic frequencies and electrical noise. While it is an expensive capacitor, the high performance and durability of the FCP0805C682G make it worthwhile for applications that require its features.
