Application

The B32620A3104K289 is suitable for use in applications such as power supplies, lighting systems, lighting and emergency systems. It is also suitable for low frequency high-voltage DC applications in industrial and electronic equipment. It is also perfect for AC power supplies, linear and switching power supplies, communication systems, household devices, LCD television sets, and other kinds of electronic products.

Working Principle

B32620A3104K289 film capacitors work on the basis of charge exchange among the conductive plates and the dielectric medium. The dielectric medium in this type of capacitors is polypropylene film to which special treatments have been applied. The plates are made from a strip of aluminum metal. When a voltage is applied to the plates, the electric field established due to the applied voltage causes electrons to move from one plate to the other through the dielectric medium, leading to a net charge exchange. The result of this charge exchange is the accumulation of electric charge on the plates, which gives rise to the capacitance of the capacitor.

The capacitance of the B32620A3104K289 film capacitor is affected by the distance between the plates and the dielectric constant of the material. When the distance between the plates is increased, the capacitance reduces. The dielectric constant has a direct relationship with the capacitance of the capacitor, meaning that a capacitor with a higher dielectric constant will result in higher capacitance. Also, the capacitance is also affected by the area of the plates. A larger surface area will result in higher capacitance.
