In addition, it can be used as a timing capacitor, a filter capacitor and an audio filter capacitor.

Working Principle

B32912A3154K000 is a metallized polyester film capacitor with aluminum foil and non-aqueous electrolytes. It has a self-healing characteristic, which can prevent circuits from permanent damage due to short circuit or overvoltage. When these conditions occur, the film capacitor can recover automatically. The working principle of this capacitor is based on its dielectric properties. The capacitor allows a flow of current through its plates when a voltage is applied. The current flow creates an electric field between the plates, which affects the capacitance of the capacitor.

The capacitance of the B32912A3154K000 is determined by a number of factors, including the dielectric material, the dielectric thickness, the surface area of the plates, and the distance between the plates. The dielectric material is the most important factor, as this determines the permittivity of the capacitor, which affects the capacitance. The other factors determine the capacitance indirectly. The capacitance of the B32912A3154K000 is usually between 0.1 and 0.3µF.
