Q: What is a metalized polyester film capacitor?
A: Metalized film capacitors are capacitors made of organic plastic film as the dielectric, metalized film as the electrode, and made by winding (except for the laminated structure). The films used in metalized film capacitors include polyethylene and poly Acrylic, polycarbonate, etc., in addition to the winding type, there are also laminated types. Film capacitors with polyester film as the dielectric are called metallized polyester film capacitors.
Q: What is the difference between film capacitors and electrolytic capacitors?
A: The difference between film capacitors and electrolytic capacitors lies mainly in their own composition materials and characteristics. Film capacitors are composed of metal aluminum and other metal foil electrodes and plastic film. The characteristics of film capacitors are non-polarity, high insulation resistance, and frequency. Covering a wide range, etc.
A: Electrolytic capacitors are composed of metal aluminum or tantalum as the positive electrode, liquid or solid electrolyte and other electrical materials as the negative electrode, and the intermediate metal oxide film dielectric. The electrolytic capacitor is characterized by large volume and large capacity per unit volume.
