Film capacitors, commonly known as film caps or plastic caps, are an electronic component class composed of an insulating film and two electrodes. BFC237521273 film capacitor is one of the film capacitors, whose application field and working principle will be discussed in this article.

BFC237521273 film capacitor has a maximum working voltage of 400VDC, a capacitance of 4700μF, and a temperature range of -40~+85℃. Therefore, it is suitable for a wide variety of applications, such as motor control, high-voltage DC power supply, converter systems, voltage regulation, active power filters, frequency converters, uninterruptible power supplies, inverters, and voltage/frequency stabilization.

The working principle of a BFC237521273 film capacitor is similar to that of an electrolytic capacitor. It consists of a wound structure of insulated metal foil and plastic insulation films. The metal foils are the electrodes, and the plastic films are the dielectric materials. The metal foil is electroplated with an oxide layer as a dielectric layer. When DC voltage is applied, a electric field is established between the metal foils, which then stores electrical charge as a capacitor.

The main advantages of the BFC237521273 film capacitor include its long service life, high ripple current, low ESR, low loss, and good frequency characteristics. These characteristics make it an ideal choice for applications that require high reliability and long-term durability. Additionally, it is also resistant to vibration, shock, temperature and humidity.

In summary, the BFC237521273 film capacitor is a versatile component with high reliability and durability. It is suitable for a wide range of applications, such as motor control, active power filters, and voltage/frequency stabilization. Moreover, it has excellent electrical properties, such as low ESR, high ripple current, and low loss.
