Film capacitors are widely used in electrical and electronic devices due to their excellent capacitance stability, superior insulation properties, and ability to withstand voltages up to 6.3kV. The B32620A6472J289 is a polypropylene film capacitor that is UL-approved for capacitor applications, and is available in ratings from 0.022μF to 0.47μF at a rated voltage of 630VAC (250Vrms).

This capacitor is designed to provide high capacitance values in a compact form factor and is used primarily in AC-coupling, AC-bypass, or timing circuits. Common applications include motor controls, AC motor starters, output rectification and voice signal processing.

The B32620A6472J289 capacitor is constructed from a polypropylene film dielectric that has a low dissipation factor and a high tolerance for temperature extremes. The dielectric is sandwiched between two aluminum electrodes with a strong adhesive, creating a ‘sandwich’ capacitor with excellent insulation properties. The capacitor construction is then protected by a radial coat of wax for improved stability and moisture protection.

The working principle of the capacitor is based on the electrochemical phenomenon known as capacitance. Essentially, this occurs when two charged surfaces, typically made up of an electrolyte material, are separated by a non-conductive material. The charges on the two surfaces attract each other, creating an electrical field. When a voltage is applied to a capacitor, an electric current flows through the capacitor, resulting in the accumulation of charge on the two surfaces. The amount of accumulated charge or the capacitance of the capacitor is determined by the area of the two surfaces and the distance between them.

The B32620A6472J289 capacitor is designed to provide a maximum capacitance of 0.47 microfarads at a rated voltage of 630VAC (250Vrms). The high capacitance and voltage ratings make this capacitor well suited for use in industrial and automotive applications, as well as for EMI/RFI filtering and high frequency timing applications.

Overall, the B32620A6472J289 is an excellent choice for use in AC-coupling, AC-bypass, motor controls, and output rectification applications due to its compact form factor, high capacitance value, and excellent insulation capabilities. This capacitor is UL-approved for capacitor applications and is highly reliable. The combination of these features makes the B32620A6472J289 an ideal choice for a variety of applications.
