GB/T 10188-2013 is a sub-specification for fixed capacitors for electronic equipment. It focuses on metal foil polypropylene (PP) film dielectric DC fixed capacitors, specifying the classification, technical requirements, test methods and inspection rules of this type of capacitors. In terms of technical requirements, it covers electrical performance such as capacitance range, Rated voltage, loss angle tangent, as well as Appearance, size, etc. It provides a unified standard for the production and mass testing of such capacitors to ensure that they can stably meet the needs of DC circuits in electronic equipment.
