Working Principle

B32529C6222J000 is a three-terminal electrical component. In a capacitor, the electric charge accumulation is called capacitance. B32529C6222J000 is made of a layer of polypropylene film as the dielectric between two thin metal layers, and its capacitance is formed by the interaction between the two conducting surfaces.

When the capacitor is connected to the AC power supply, the capacitor allows the current to pass on one side at a certain frequency, and stores the energy in the capacitor when alternating current reverses to the other side. At this moment, the current in the capacitor leads the current in the input circuit. The capacitor has two terminals, and works like a resistor whose resistance value changes with the frequency variation.

B32529C6222J000 can also be connected in parallel (or in series) to form a filter circuit. When two or more capacitors are connected in parallel, the capacitance changes. As a result, the filter circuit can block higher frequency signals and works like a low pass filter to pass lower frequency signals.
