This part of GB/T 6346 applies to surface-mounted conductive polymer solid electrolyte tantalum fixed capacitors (hereinafter referred to as capacitors).

Surface mount MnO2 solid electrolyte tantalum fixed capacitors are not included in this section, but are covered by IEC 60384-3.

This type of capacitor is mainly used for direct mounting on hybrid circuit substrates or printed circuit boards.

Capacitors for special purpose applications may require supplementary technical conditions.

1.2 Purpose

The purpose of this part is to specify priority ratings and characteristics for this type of capacitor, and to select the applicable quality from IEC 60384-1.

Evaluation procedures, test and measurement methods, and general performance requirements for this type of capacitor are given. Refer to the detailed specifications in this section

The specified test severity and requirements should have the same or higher performance level, and it is not allowed to reduce the performance level.
