GB/T 46822.2-2025 Fixed electric double-layer capacitors for use in electric and electronic equipment—Part 2:Sectional specification—Electric double-layer capacitors for power application
Basic Information
Scope
This document specifies the priority rated values and characteristics of power-type double-layer capacitors, selects applicable quality assessment procedures, test and measurement methods from GB/T 46822.1—2025, and provides general performance requirements for such capacitors. The test severity levels and requirements specified in the detailed specifications referenced in this document provide the same or higher performance levels.
This document applies to power-type double-layer capacitors.
Power-type double-layer capacitors are suitable for applications requiring discharge currents ranging from milliamps (mA) to amps (A). The characteristics of the capacitors include relatively high capacitance and low internal resistance, making them suitable for Classes 3 and 5 specified in the measurement categories defined in GB/T 46822.1—2025.
The calculation procedure for power density is provided in Appendix A.
