Composition, Characteristics, Principles, Common Faults, and Preventive Measures of Film Capacitors 2

4. Classification:

-Classified by material: polypropylene film capacitors, CS4385-CQZ polyester film capacitors, etc;

-Classified by structure: foil film capacitors, trapezoidal film capacitors, etc;  diode

-Classified by purpose: coupling capacitors, DC filtering capacitors, etc.

5. Common faults and preventive measures:

-Common faults: capacitance drift, increased leakage current, short circuit, etc;

-Preventive measures: Strictly control the production process, improve the dryness of the working environment, control the working temperature, etc.

Summary: Thin film capacitors, as an important electronic component, have been widely used in various electronic fields. Understanding its composition, characteristics, principles, classification, common faults, and preventive measures is helpful for the correct selection, use, and maintenance of thin film capacitors.diode
