It is made using a polypropylene dielectric and features board-level temperature stability, low losses, high insulation resistance, excellent heat and humidity resistance, low ESR, and a long service life. The capacitor is designed to withstand a temperature range of -55°C to +105°C.

This device is most commonly used for low frequency analog signal or power conversion applications, and can be found in a variety of industries, such as:

• Military/Aerospace
• Communication equipment
• Medical equipment
• Consumer electronics
• Industrial control systems

Working Principle

Film capacitors work based on the same principles as other types of capacitors. They work by storing energy in an electric field, which is created when two conductive surfaces are separated by an insulating material. The insulating material used in film capacitors is a plastic film, which is chosen because it offers the best combination of insulation and capacitance performance.

In the case of the BFC237261333, the plastic film used is polypropylene, which offers high temperature resistance and excellent dielectric properties. The polypropylene film provides excellent heat and humidity resistance, low losses, and a long service life, making it a great choice for low-frequency analog applications.

The two conductive surfaces of the capacitor are typically made of aluminum foil, which is chosen because of its excellent electrical and thermal properties. The conductive surfaces are coated with a thin layer of conductive material, such as silver or tin-plated copper, to improve their conductivity.

When there is a voltage difference across the capacitor, it creates an electric field in between the conductive plates. This field stores energy, which can then be released when the voltage is removed. This is the basic working principle behind film capacitors, like the BFC237261333.
