What is the difference between metallized capacitor and metal film capacitor?
Aluminum electrolytic capacitor common aluminum electrolytic capacitor, it is made of aluminum cylinder, which contains liquid electrolyte, made of a layer of aluminum foil, a layer of insulation coil. Or through the DC voltage treatment, the pole of the film on the formation of an oxide film as a medium. The utility model has the advantages of large capacity, large leakage, poor stability, positive and negative polarity, and is suitable for power supply filtering or low frequency circuits. When using, the positive and negative electrodes do not connect with the reverse.
Metallized film capacitor is a metallized film capacitor that is rolled or laminated with a double-sided metallized polypropylene film and a non - metallized polypropylene film
