Welcome to the official website of Zhizhong Electronics Co., Ltd.Company focus: Ceramic Capacitor, Monolithic capacitor

The naming of polyester film capacitors is mainly a classification of capacitor models in China's industry standards. At present, many industry standards have been replaced by GB. There is no compulsory meaning.
　　 The three models of CBB61/CBB65/CBB60 are all AC motor capacitors. Polyester film capacitors are mainly distinguished from their use and appearance. It is an industry habit in China. 61 is mainly square mainly used for fans, 60 and 65 are mainly round, 60 is mainly used for motors, and 65 is mainly used for running capacitors on air conditioners and refrigerators, with explosion-proof function. These explanations are more and more just a habit of implementing the gb/T3667 standard. CBB20/CLDR/ CBB21 These capacitors are the same as above and mainly implement the standard GB T 14472 or GB T 2693. Among them, the CLDR model is the most convincing and can be understood as a polyester film capacitor (CL-polyester film, CBB-metal polyester film capacitor). At present, in terms of internationalization, this is a model name of the manufacturer's own, which is easy to retrieve. The most important requirements of users are: what standards are implemented; what installation dimensions are required by the enterprise, and whether they have explosion-proof levels, etc. Whether or not to obtain certification is the most important thing. For example, if you apply for the CBB65 model, it will be this model when you are certified by all countries. You can call this capacitor type YY-1 when you certify it, but the type of the capacitor is YY-1 type. These polyester film capacitor models are the product standardization of China's industry standards. At present, every company is not implementing industry standards, so this standard is not restricted. Rely on our own company to standardize.
Model and product certification
　　The most important thing is the environment in which these polyester film capacitor products are used, and what kind of implementation standards the manufacturer will give. Or which certifications are obtained and which standards are implemented. At present, the types of capacitors produced at home and abroad cannot be unified, and users must purchase them according to requirements.
