Working Principle of B32686S7474K561 Film Capacitor

B32686S7474K561 film capacitor is based on plastic films such as polyester, polypropylene and polycarbonate. Its electrodes are made of aluminum foil, which is the key to ensure the stable characteristics of the capacitor. The working principle is that when the capacitor is charged, the positive and negative charges attract each other on the two electrodes. The accumulation of charges which generate a potential difference between two electrodes creates an electric field. At the same time, when the capacitor is connected to the signal source, the current will flow through and around the dielectric between the two electrodes until the charge and neutralization balance each other out, resulting in the capacitor\'s capacitance value. In addition, when B32686S7474K561 capacitor is in the process of charging and discharging, an electric current will also arise, and it will be converted instantly, thus suppressing a large voltage fluctuation. This is the essence of the capacitor\'s working principle.
