Film Capacitors

BFC237662134 application field and working principle

Film capacitors are type of capacitors, also known as dielectric film capacitors, plastic film capacitors, polyester film capacitors, polypropylene film capacitors and paper/oil capacitors. Enhanced with a dielectric film made of plastic, polyester, polypropylene or paper, these functional capacitors are used as filters, coupling, triboelectric modification and other capacitance-related tasks.

BFC237662134 is polypropylene film capacitor presented by Bulgin in the EEF range. This polypropylene film capacitor is highly reliable, having a high voltage rating and capacitance. It has a lead spacing of 37.3mm, a voltage rating of 250V, a capacitance of 0.0022 μF and a tolerance of ±5% for accuracy. This BFC237662134 film capacitor is ideal for applications in industrial and commercial machines like HVAC, pumps and fans.

Working principle

A film capacitor is an electronic component made of two or more conductive metal plates, separated by a thin insulating dielectric material. When a voltage is applied to the two metal plates of a film capacitor, electrostatic force causes the metal to store charge. This static charge can then be used to store energy for a short period of time.

At the same time, the force of attraction between these two charged plates causes the electrical field in the dielectric material to increase. This increases the charge energy stored by the metal plates and increases the capacitance of the film. When the voltage is removed from the plates, the force of attraction between them disappears and the capacitance returns to its original value.

In the BFC237662134, the capacitance is adjustable. This is achieved by controlling the gap between the two metal plates. When the gap is reduced, the capacitance increases. Similarly, when the gap is increased, the capacitance decreases. The capacitance can also be adjusted by adjusting the pressure on the plates, which affects the dielectric material between the plates.

Applications

The BFC237662134 polypropylene film capacitor is ideal for use in high voltage applications such as HVAC, pumps and fans, where accuracy and precision is essential. It can also be used for motor start applications. With its high voltage rating and capacitance, the BFC237662134 is the perfect choice for applications requiring large amounts of energy and space. It is also ideal for use in switching power supplies, snubbers, EMI and RFI filters, and coupling and decoupling of multiple power lines.

In addition to its application in high voltage AC applications, the BFC237662134 can also be used in DC applications. For those requiring higher precision, the capacitor can be used in digital circuits where accuracy is vital. The BFC237662134 is also suitable for use in harmonic filters, pulse and delay circuits as well as AC rectifiers.

Conclusion

The BFC237662134 polypropylene film capacitor is a reliable component with a high voltage rating and capacitance. It is ideal for use in a wide range of applications, from AC and DC rectifiers to high voltage AC applications such as HVAC.
