Film Capacitors

Film capacitors, also known as film dielectric capacitors, are components used to store electrical energy, filter noise, and are well-suited to high temperature and high voltage applications. They have been in use since the mid-20th century and are identified by their type number BFC236657183. Their application fields and working principle will be explored below.

Application Fields

Film capacitors generally offer very good performance in high voltage applications. They often have higher insulation resistance and breakdown voltage ratings than other types of capacitors, making them ideal for applications requiring a high degree of protection such as motor control, telecoms, switchgear, and medical equipment. Additionally, their low leakage current makes them suitable for filtering low-level signals. Due to their greater stability over temperature, they are also beneficial in temperature sensitive electronics.

Working Principle

The BFC236657183 film capacitor is composed of two plates that are separated by a polyester or polypropylene film. A metalized surface is then applied to each plate, which increases its surface area and allows more charge to be stored. When voltage is applied to the capacitor, electrons flow from the metalized surface into the film and cause an electric field within the film. This electric field stores electrical energy in the form of electric dipoles, which make up the capacitor’s capacitance. The amount of charge stored in the film depends on the size of the metalized surfaces, the distance between them, and the dielectric constant of the film material.

Benefits of Using BFC236657183 Capacitors

The BFC236657183 film capacitors offer many benefits. They can operate at higher temperatures than traditional ceramic capacitors while maintaining a higher amount of capacitance. They are very stable, with small changes in capacitance over temperature and voltage, and their non-polarized design means that they require less space than electrolytic capacitors. Additionally, their rugged construction makes them resistant to vibration, shock and other mechanical stresses.

Conclusion

The BFC236657183 film capacitor is an ideal component for many application including high voltage, temperature sensitive and low level signal filtering. These capacitors offer a number of benefits, including higher temperature operation, small size, stability and ruggedness. With their wide range of applications, their popularity is likely to continue in the years to come.
