Film capacitors, also known as Polypropylene Film Capacitors, emerged in the early 1970s. They are widely used for their unique characteristics such as high capacitance, high frequency and electrical stability when compared to other capacitor types. In particular, the FCP0805H221G film capacitor has become a popular choice in many applications due to its low price and small size. Below is an introduction to the application field and working principle of the FCP0805H221G.

The FCP0805H221G is suitable for high frequency and high temperature applications, including in automotive electronics, home appliances, industrial electronics, power supplies, OA equipment, and more. It also has excellent properties of high insulation resistance, low dielectric loss, low temperature coefficient, and high reliability. The FCP0805H221G is one of the most cost-effective and widely used film capacitors today.

The working principle of the FCP0805H221G film capacitor is based on the structure of a dielectric layer sandwiched between two electrodes. During the operation of the film capacitor, electric charge will flow from one electrode to the other, with the dielectric layer providing insulation between the two electrodes. As the voltage across the electrodes increases or decreases, the electric charge will be stored or discharged, respectively. This storage and discharge of electrical charges is the basic working principle of a film capacitor and the same process also applies to the FCP0805H221G.

The FCP0805H221G has a 0.8mm diameter, 0.5mm height cylinder with two conducting leads connected to each side. It is mounted on a printed circuit board and the body is insulated from the board by an electrically insulating material, such as a dielectric layer. The two leads are connected to the sides of the film capacitor and the voltage applied across them will create electric fields between them. These electric fields cause the two metal electrodes to charge and discharge, thus providing the capacitive effect.

In summary, the FCP0805H221G is suitable for high frequency and high temperature applications, due to its excellent properties of high insulation resistance, low dielectric loss, low temperature coefficient, and high reliability. Its working principle is based on the structure of a dielectric layer sandwiched between two electrodes, which allows the capacitor to store and discharge electrical charges. The FCP0805H221G film capacitor is compact and highly cost-effective, making it a popular choice in many applications.
