Working Principle of B32671P4154K189 Film Capacitors

The working principle of the B32671P4154K189 film capacitor is based on the modulation principle of the electromagnetic field. When an alternating voltage is applied to the film capacitor, an electric field is generated between the two plates, and the electric field moves the electrons inside the capacitor.

The electrons will accelerate back and forth between the two plates at high speed. This process will generate an opposing electromagnetic field, which in turn will reduce the electric field generated by the applied voltage. This process will repeat cyclically, and the capacitance of the film capacitor will remain constant.

When the B32671P4154K189 film capacitor is used in the power supply circuit, its role is to absorb and store the current in the circuit, and maintain a constant voltage in the circuit. In DC filter circuits, the capacitance of the film capacitor can be used to reduce the signal ripple.In high-order low-pass filter circuits, the B32671P4154K189 film capacitor can be used to reduce the signal ripple at high frequencies. In switching power supply circuits, the B32671P4154K189 film capacitor can be used to filter the noise generated by the switching power supply.
