Film capacitors are advanced electronic components used in a variety of applications, particularly in the medical, aerospace and telecommunication industries where precise parameters and reliable operation are desired. FCP0805H821J is an example of a film capacitor, and it is widely used for its capacitance and size advantage. In this article, the application field and working principle of FCP0805H821J will be discussed.

Application Field of FCP0805H821J

FCP0805H821J is a film capacitor manufactured by a multinational components supplier. It is used in many applications, including medical apparatuses, aerospace systems, telecommunication equipment, portable audio devices, and consumer electronics. The capacitor comes in a variety of sizes and shapes to meet the requirements of these applications. The FCP0805H821J, for instance, has a 0805 case size, is rated at 0.82 nanofarads (nF) and can operate at temperatures between -55 to +125°C.

FCP0805H821J is a high-capacitance, tubular-style capacitor, which means that it contains a large amount of conducting material inside a plastic tube-like case. As a result, it can handle higher voltages than a standard ceramic capacitor. Additionally, the tubular shape of FCP0805H821J makes it better suited for applications with space constraints, such as in medical apparatus and other portable electronic devices. Moreover, the component is manufactured with high precision which ensures accuracy and reliability.

Working Principle of FCP0805H821J

A film capacitor is an electronic component that is made up of two conductive plates that are separated by a dielectric material. This dielectric is usually a thin sheet of plastic-like material, although sometimes it can be a film-like material such as polyethylene. When an electric voltage is applied across these plates, an electrical field is created. This field causes electrons to move from one plate to the other. This movement of electrons creates a capacitance between the two plates.

The amount of capacitance present in a film capacitor is directly related to the thickness of the dielectric material. The thicker the material, the greater the capacitance. FCP0805H821J has a dielectric made of polyethylene film, which is very thin compared to other types of dielectric materials. As a result, it has a very low capacitance (0.82 nF). However, this also means that the FCP0805H821J is able to handle higher voltages without breaking down or suffering any damage.

Additionally, the FCP0805H821J is also designed to be resistant to temperature variation. As capacitance is temperature-dependent, the FCP0805H821J is able to remain stable from -55°C up to 125°C. This makes it suitable for use in extreme temperatures, which again makes it ideal for use in medical applications and other precision electronics.

Conclusion

FCP0805H821J is a film capacitor that has a variety of applications in medical apparatuses, aerospace systems, telecommunication equipment, portable audio devices, and consumer electronics. The component has superior capacitance and temperature stability due to its thin polyethylene dielectric film. Additionally, the tubular style of FCP0805H821J makes it well-suited for applications with space constraints. The component is reliable and precise, making it suitable for high-performance, and demanding environments.
