Film Capacitors

The BFC233990017 film capacitor is an especially versatile electrical component that is used in a wide variety of applications because of its impeccable performance and reliability. Film capacitors are desirable in many applications due to their very low equivalent series resistance, and low self-inductance. The BFC233990017 film capacitor has a number of special attributes that set it apart from the rest.

The BFC233990017 film capacitor is a metalized polypropylene film capacitor and is known for its very high dielectric strength. The insulation characteristics of the capacitor are superior, as it has the ability to withstand voltages in excess of 3000VAC. The BFC233990017 also has excellent self-healing capability, meaning that it can recover from over-voltage and surge conditions quickly. Its lifetime is also very impressive, with rated service lengths up to 1500 hours or 1,000,000 switching cycles.

Application Field

The BFC233990017 film capacitor can be used in a wide range of applications. It is often used in automotive, industrial, medical, and consumer electronics applications. It is particularly useful in synchronous motors because of its very low equivalent series resistance, enabling it to operate at high frequencies and higher torques. It can also be used in lighting applications to limit inrush current and provide stable power to lighting circuits. Its high dielectric strength allows it to be used to improve the performance and reliability of voltage output from power supplies.

Working Principle

A film capacitor is composed of three components: two metalized layers of conductive material and one layer of dielectric material in between them. When an electric current is applied, the metalized layers store up opposite charges and form an electrical field. The dielectric material prevents the electric charges from leaking away, thereby storing the charges even after the electric current has been removed. The stored energy is then returned to the circuits as the electric current changes polarity.

The BFC233990017 film capacitor works on the same principle, but with improved insulation characteristics, higher capacitance, and lower impedance. Its thin dielectric material, embedded with metalized layers, ensures a very high dielectric strength. The metalized layers also allow it to absorb more energy, resulting in a higher capacitance. Additionally, its lower impedance ensures that it can handle higher frequencies and higher speeds with increased stability and reliability.
