Film Capacitors

Film capacitors, also known as plastic film capacitors or metalized film capacitors, are constructed from a thin polyester (PET) or polypropylene (PP) film between two plates. They are divided into two distinct types: non-polarized and polarized. Like electrolytic capacitors, polarized film capacitors require correct polarity during operation. Unlike electrolytic capacitors, non-polarized film capacitors provide a more reliable, consistent, and predictable performance in terms of voltage, temperature, and frequency range.

BFC237121154 Application Field and Working Principle

The BFC237121154 is a specialized film capacitor. The capacitor has a voltage rating of 400V, a capacitance of 100uF, and a dielectric loss of 0.003%. These features make it suitable for a range of high-precision applications including audio equipment, power supplies, and microcontroller-based devices. It is also compatible with extremely low temperatures and has excellent low-temperature stability.

The BFC237121154 uses a metallized film as its dielectric material. This film has a combination of metallized aluminum (Al) and polyester which is used to form an extremely thin and homogeneous electrode. The thin construction allows for better energy flow while providing a more reliable performance. The combined aluminum film and polyester provides excellent insulation and helps to reduce the size of the capacitor.

The working principle of the BFC237121154 is similar to other film capacitors. The capacitor works by passing a current from one electrode to the other. This creates an electric field that stores energy and then discharges it when the current is removed. This arrangement allows the capacitor to absorb and store charge, while also releasing it as necessary.

In addition to its reliable performance, the BFC237121154 also offers excellent frequency range and excellent dielectric strength. This makes it suitable for high-precision applications such as audio equipment and power supplies. The capacitor can also withstand extreme temperatures without suffering any damage or losing its performance.

Overall, the BFC237121154 is a specialized film capacitor that can be used for a wide range of high-precision applications. Its features and excellent performance makes it particularly suitable for audio applications and other applications that require a high degree of accuracy and reliability.
