What Does CBB60 Mean on a Capacitor?   If you work with motors, HVAC systems, or household appliances, you may have come across capacitors labeled CBB60. But what exactly does CBB60 mean, and how is this type of capacitor used in practical applications?  This article explains the meaning of CBB60, its structure, and where it is commonly applied.   Understanding the CBB60 Code The term CBB60 is a model designation commonly used for AC motor run capacitors. Each part of the code carries specific technical meaning:  CBB – Indicates a metallized polypropylene film capacitor  “CB” refers to film capacitors  “B” specifies polypropylene as the dielectric material  60 – Refers to the application category, typically associated w...

In film capacitor manufacturing, electrical performance and long-term reliability are fundamentally determined by the quality of the dielectric film. While external dimensions and rated values are easy to specify, the real performance of a capacitor depends on how well the dielectric material performs under electrical stress, thermal cycling, and continuous operation. For applications such as motor run capacitors, power supplies, and industrial electronics, proper dielectric film selection is not simply a material choice—it is a critical engineering decision that directly affects stability, efficiency, and service life.     The Role of Dielectric Film in Film Capacitors The dielectric film acts as the insulating medium between capacitor electrodes and defines the capacitor...
