Film capacitors are steadily replacing aluminum electrolytic and ceramic capacitors in motor drives, lighting systems, switch mode power supplies, and other applications in the industrial and consumer electronics market. The BFC237545562 is one of the film capacitors in the BFC series from Vishay, and is designed for applications demanding high performance in terms of reliability and effiiciency.

Applications

The BFC237545562 film capacitor is commonly used for power control and motor drive applications due to its high surge current capability and robust construction due to its biaxially oriented, polypropylene film dielectric. It is also suitable for use in electronic lighting, high frequency, and high efficiency applications, where high reliability, low ESR (Equivalent Series Resistance), and low ESL (Equivalent Series Inductance) are necessary.

Working Principle

The BFC237545562 film capacitor is a tubular capacitor that consists of two electrodes crimped on either end of a polypropylene film, with a resilient epoxy end seal. The polypropylene film acts as the dielectric for the capacitor, and the metallic layers of the electrodes provide the two poles of the capacitor. The film in between the electrodes stores electrical energy in accordance with the equation I*C = Q, where C is the capacitance of the capacitor, and Q is the charge stored.

The construction of the BFC237545562 capacitors provides higher electrical stability and high pulse withstand capability when compared to other types of capacitors. The device is also durable, resistant to shock, and has excellent frequency characteristics. Its high stability and reliability make it suitable for use in lighting drives, switch mode power supplies, and other applications sensitive to low ESR and low ESL.

The BFC237545562 film capacitor is designed with a self-healing construction, which prevents shock and possible electrical damage due to over-voltage and high energy spikes. Additionally, the construction of the capacitor allows it to self-correct any minor surface defects on the polypropylene film, ensuring its dependability and longevity.

Thanks to its reliable design and long-term durability, the BFC237545562 film capacitor is known for its high operational efficiency, making it the ideal choice for power circuits and motor drives, audio applications, and other electronics applications requiring long-term reliability and performance.
