At 85°C the lifetime is derated further; continuous operation at the upper limit is not recommended. Radial through-hole can, 13.60 mm x 6.30 mm body, 0.354\" (9.00 mm) lead spacing — fits standard 0.1\" pitch prototyping grids and most PCB layouts for cylindrical supercapacitors. Seated height of 0.610\" (15.50 mm) above the board — allow clearance for the vent at the top of the can; do not pot or conformally coat the vent area. PC pin termination: the leads are designed for wave soldering; hand-solder with a temperature-controlled iron at 350°C max, dwell under 5 seconds per joint to avoid damaging the internal seal. No pin-compatible direct replacement is listed in the SCM family — the SCMQ14D474PRBB0 is the specific capacitance/voltage/ESR variant for this footprint. If the line needs a faster alternative, the SCM series includes lower-ESR options at the same voltage but different capacitance values; verify the hold-up time budget before substituting.","metaTitle":"KYOCERA AVX SCMQ14D474PRBB0 Supercapacitor, 470 mF, 5.4 V","metaDescription":"Active production supercapacitor from KYOCERA AVX, 470 mF capacitance, 5.4 V rated, 400 mOhm ESR.
