Working Principle of B32776G8156K000 Film Capacitor

The B32776G8156K000 is a metallized polyethylene terephthalate film capacitor. It has two electrodes that are separated by an insulation film made of polyethylene terephthalate. This type of capacitor is non-polarized and offers good performance even at high frequencies. The insulation film and electrodes are both coated with thick layers of metal, usually aluminum.

When a voltage is applied to the two electrodes of the capacitor, the electrical current flows through the metal layers and creates an electrostatic field around the electrodes. This electrostatic field creates a capacitive reactance which results in the capacitor storing electrical energy. This stored energy is then released when the voltage is removed from the capacitor.

The B32776G8156K000 film capacitor is highly reliable and has excellent temperature, frequency and power characteristics. It is also resistant to most chemicals and can be used in harsh environments.
