Film capacitors, also known as plastic film capacitors, are constructed using multiple thin layers of polymer films as dielectric materials, separated by a thin metal foil. The most common film used for the dielectric material in film capacitors is polyester, and it is this type of capacitor that is rated with a BFC237517163 part number.

Film capacitors are used in many different applications, and are a popular choice due to their robustness, good insulation performance, low bulk-capacitance, low leakage, high operating temperature, and low cost. Common applications for film capacitors include circuits with high frequency interference, power conditioning, and monitoring of high voltage DC circuits.

Polyester film capacitors are manufactured using a variety of winding techniques and processes. In the simplest design, the metal foil and dielectric film are wound together in the shape of a cylindrical core. The core is then placed into a container and tested for capacitance and insulation resistance. By changing the number of film layers used in the winding process, or by changing the winding technique, the electrical properties of the capacitor can be adjusted.

The working principle of the BFC237517163 part number film capacitor is based on a capacitive effect. When the capacitance is increased, the coupling of charge between two conductive plates is increased, and the current flow between them is significantly increased. The capacitance is determined by the combination of the distance between the two conductors, the cross-sectional area of the conductors, and the dielectric material used between the plates.

The main advantages of the polyester film capacitor are its ability to withstand high temperatures, its low electrical leakage, and its low bulk-capacitance. The BFC237517163 capacitor is rated for operation in temperatures up to 85°C. Additionally, it has a low electrical leakage of only 0.2 pF/μm and a low bulk-capacitance of only 0.1pF/μm. This is why the BFC237517163 part number is often used in high temperature, high frequency circuits.

The BFC237517163 part number is commonly used in applications that require high frequency interference, power conditioning, and monitoring of high voltage DC circuits. Due to its low impedance and low cost, it can also be used in circuits with high current flow, such as those used in audio equipment. Additionally, film capacitors are widely used in motor speed control systems and in automotive electronics.

In summary, the BFC237517163 part number is a polyester film capacitor that is designed for use in many different applications. It has a low electrical leakage, a low bulk-capacitance, and can operate in high temperatures. Additionally, it has a low impedance, which makes it suitable for use in audio equipment, motor speed control systems, and automotive electronics.
