Polyester capacitor are basic components of electronic products with polyester as the medium, and are used in various DC or low-frequency pulsating circuits. Polyester capacitor have high dielectric constant, small size, large capacity, and good stability. They are suitable for bypass capacitors; the price-capacity ratio and the volume-to-volume ratio are larger than electrolytic capacitors and ceramic capacitors.
Characteristics of polyester capacitors:
- Small size and light weight;
- Good stability and high reliability;
- The lead wire is directly welded to the electrode with low loss;
- Sensitive structure, encapsulated by polyester film and epoxy resin.
Advantages: The accuracy, loss angle, insulation resistance, temperature characteristics, reliability and environmental adaptability of film capacitors are better than electrolytic capacitors and ceramic capacitors.
use:
It is suitable for use in various DC or low-frequency pulsating circuits.
