capacitor is made of organic plastic film as dielectric, metal foil or metallized film as electrode by winding (except laminated structure), among which polyester film and polypropylene film are the most widely used.
the naming rules of national standard for film capacitor models are as follows:
at present, the domestic production of organic film capacitor mainly includes polyester film capacitor and polypropylene film capacitor. there are more than 100 production enterprises, and state-owned, collective and foreign-funded enterprises coexist. the development of foreign-funded enterprises is rapid. the production is still dominated by traditional linear products, followed by small and ultra small ones, and chip products are still in the research and development stage.
the naming rules of national standard for thin film capacitors are as follows:
1. cl11 - inductive foil polyester film capacitor;
2. cl12 - non inductive foil polyester film capacitor;
3. cl21 - non inductive metallized polyester film capacitor (cl21x is a miniaturized product);
4. cl20 - metallized axial lead polyester film capacitor;
5. cbb13 - non inductive foil polypropylene film capacitor;
6. cbb21 - non inductive metallized polypropylene film capacitor;
7. cbb81 film / foil series high voltage polypropylene film capacitor;
8. cbb62 - ac metallized polypropylene film capacitor (also called x capacitor);
9. cbb20 - metallized axial lead polypropylene film capacitor;
10. ch11 - inductive, polyester film 1 polypropylene film composite dielectric capacitor.
thin film capacitors are mainly used in electronics, household appliances, communications, electric power, electrified railway, hybrid electric vehicles, wind power generation, solar power generation and other industries. the stable development of these industries has promoted the growth of thin film capacitor market.
