Film Capacitors

Film capacitors, also known as plastic film capacitors, plastic film capacitors, or dielectric film capacitors, are a kind of non-polarized capacitor with a thin plastic film as the dielectric. They are mainly used to stabilize electrical waveforms or protect circuits from transients. Film capacitors are available in various values, including the BFC237945473 series.

BFC237945473 Application Field and Working Principle

The BFC237945473 series is composed of CBB60 and CBB61 film capacitors, used for the insulation, filter connection, and surge protection of lighting equipment. This series uses PP (Polypropylene) film, aluminum electrolytic paper, and metalized polyethylene naphthenate(M/PEN) film as the dielectric material, and is wound on polymide film to form an electrode structure. The series has characteristics that are highly resistant to temperature and humidity, with good linearity and self-healing properties, and high capacity.

The BFC237945473 series works by using the dielectric material in the capacitor to store electric energy and store energy in an electrical field when a voltage is applied to the two electrodes of the capacitor. This makes them excellent at filtering high frequencies, eliminating impulse noise, and stabilizing the output voltage. Since film capacitors are largely used in electrical circuits, they must have low internal losses and wear resistance, and a long operating life.

The BFC237945473 series are available in a wide range of capacitances, from 0.01μF to 150μF at rated voltages of 250, 315, 400, 500 and 630VAC. The capacitors are available either as Axial Leaded, IPP, or Screw terminal versions. Withstanding the maximum rated voltage of 630V, these capacitors also feature across-the-board dustproof and flame-retardant features. This series also has a wide temperature range of -40°C to +85°C.

The BFC237945473 series are typically used for input filter connections of power supplies, converters, lightings, and domestic appliances. Due to their excellent performance and durability, they have become popular for use in all kinds of applications.

In conclusion, BFC237945473 film capacitors are indispensable components in a variety of modern electrical circuits. They offer excellent surge protection, electrical insulation, and voltage stability, and are designed to last for many years. They are available in a wide range of values, type versions and rated voltages, and are suitable for use in many different types of applications.
