Film Capacitors

Film capacitors are electrical components which use thin, insulating film as a dielectric for their construction. The film capacitor is constructed using a number of layers of dielectric material, usually polyester, polypropylene or polyethylene. The layers are sandwiched between two conducting plates, known as electrodes. These conducting plates are then held together by a laminate sheet cover, and the whole capacitor is encased in a sealed plastic housing.

BFC238301754 Application Field and Working Principle

BFC238301754 film capacitors are mainly used in industrial control systems, electric drives, high-frequency welding machines, renewable energy systems, power distribution and control systems. They are also suitable for power supplies, switches, UPS, frequency inverters, automotive electronics, inverters, semiconductor killers, and high-energy storage.

The BFC238301754 is a polyethylene film capacitor which features high volumetric efficiency and low audible noise. It also has excellent stability and reliable operations in various conditions. The device operates on the principle of dielectric absorption. This means that when an alternating current passes through the capacitor, the dielectric medium absorbs energy and stores it for later release. As the capacitor charges and discharges, a small amount of energy is lost due to resistive and capacitive losses in the dielectric material.

The BFC238301754 capacitor is available in several ratings of capacitance, including 0.1 to 1000 uF. It has a wide operating voltage of up to 2000 volts and a high impulse voltage rating of 2000 volts. It is also high temperature rated for up to 130 degrees Celsius, making it suitable for use in a variety of environmental conditions. Additionally, the device has an ultra-low ESL with values of 0.15pF at 1kHz.

The BFC238301754 film capacitor is designed for reliable long term use in industrial automation and consumer electronics, due to its high reliability and long service life. The capacitor also has a low ESR, excellent ripple current characteristics, and a low self-heating voltage. The device is also RoHS compliant and meets IEC and UL safety requirements. In addition, the device comes with a 7-year limited warranty.
