GB/T 6346.26-2018 to formulate sub-specifications for conductive polymer solid electrolysis aluminum fixed capacitors for electronic equipment. The standard defines relevant terms and specifies product classification methods. Rated voltage, capacitance range, loss and other aspects specify electrical performance requirements, as well as mechanical and environment performance indicators. At the same time, inspection rules are given, including sampling plans, test sequences and judgment criteria. It provides the basis for the production, quality control and testing of such capacitors, which helps to ensure the stable and reliable operation of products in electronic equipment and promote the standardization of the industry.
