Naming rules for film capacitor models|Focus on mid-to-high-end brand capacitor manufacturers

by:Shenmao     2021-04-20
Film capacitors are made of organic plastic film as the medium, and metal foil or metalized film as the electrode. They are made by winding (except for laminated structure). Among them, polyester film and polypropylene film are the most widely used. National standard naming rules for film capacitor models: At present, the domestic production of organic film capacitors is mainly polyester film capacitors, polypropylene film capacitors, etc. There are more than 100 production enterprises, state-owned, collective, and foreign-funded enterprises coexist, and foreign-funded enterprises are developing rapidly. Production is still dominated by traditional linear products, followed by small and ultra-small products. Chip products are still in the research and development stage. The national standard has these rules for the model naming of film capacitors: 1. CL11-inductive foil polyester film capacitor; 2. CL12-non-inductive foil polyester film capacitor; 3. CL21-non-inductive metalized polyester film capacitor ( CL21X is a miniaturized product); 4. CL20-metalized axial lead polyester film capacitor; 5. CBB13-non-inductive foil type polypropylene film capacitor; 6. CBB21-non-inductive metalized polypropylene film capacitor; 7. CBB81-film/foil series high-voltage polypropylene film capacitors; 8.CBB62-AC metallized polypropylene film capacitors (also known as X capacitors); 9.CBB20-metallized axial lead polypropylene film capacitors; 10.CH11-Yes Inductive, polyester film/polypropylene film composite dielectric capacitor. Film capacitors are mainly used in electronics, home appliances, communications, electric power, electrified railways, hybrid vehicles, wind power, solar power and other industries. The stable development of these industries has promoted the growth of the film capacitor market.
