Film Capacitors: BFC238065432 Application Field and Working Principle

Film capacitors are widely used in various fields, such as electrical equipment, communication equipment, automotive industry, power systems, instrumentation, consumer electronic equipment and so on. BFC238065432 is a kind of film capacitor. This article will mainly talk about its application field and working principle.

Application Field of BFC238065432

The BFC238065432 films capacitor is specially designed and produced for many kinds of motor applications. It is mainly used in the following aspects:

• 1. Motor start circuit: When the motor starts, a large inrush current will be generated, and the capacitor can take on this transient peak current. Eventually, it can not only reduce the starting current of the motor, but also prevent the motor from impacting other devices.
• 2. Power Machines: The power capacity of the power machines at low frequency is relatively small, so the capacitor is used to compensate the inductance components of the motor to ensure the normal operation of the motor.
• 3. Lighting fixture: The capacitor can improve the power factor of a lighting fixture and help reduce the power loss.
• 4. AC line: The capacitor can be used to filter the high-frequency AC voltage to improve power quality.
• 5. Ultrasonic cooling: The capacitor can increase the output of the ultrasonic cooling machine by adjusting the frequency and amplitude of the drive voltage.

Working Principle of BFC238065432

The BFC238065432 film capacitor consists of two metal layers separated by a film layer. The two metal layers are conductive metal plates and the film layer is an insulating dielectric film. In the film capacitor\'s structure, the electrical charges are distributed on the conductive plates and on the dielectric surface. When the voltage is applied to the capacitor, the voltage polarity determines the internal polarization of the dielectric. When an alternating voltage is applied to the capacitor, the charges on the conductive plates will be periodically stored, and discharged through the dielectric layer, forming a periodic charging current and discharging current.

The BFC238065432 film capacitor has a low capacitor equivalent series inductance (ESL) and a low capacitor ESR (Equivalent Series Resistance). The ESL and the ESR of this capacitor are very low, making the filament capacitor especially suitable for high-frequency applications.
