120 F at 2.7 V — energy buffer for short-duration hold-up
The KYOCERA AVX SCCW50B127SSBLE is a 120 F, 2.7 V supercapacitor from the SCC LE series, packaged in a through-hole radial can with solder lug terminals. That capacitance and voltage pair stores about 437 J — enough to ride through a 100 ms power dip at 4.3 kW or supply a pulsed load like a GSM burst without dragging down the main rail. The ESR is 6 mOhm at 1 kHz, which keeps the voltage drop under 0.6 V during a 100 A pulse — the limiting factor in a supercap bank is often the IR drop, not the total stored energy. For a 120 F cell, that ESR is low enough that a single device can handle peak currents that would normally need a parallel stack.
Through-hole solder lug — board-fit and thermal path
Operating temperature spans -40°C to 65°C, with a rated lifetime of 1000 hours at 60°C. That 1000-hour figure is the accelerated-test endpoint — at 40°C ambient the expected life roughly doubles per 10°C derating, so in a 40°C enclosure the part runs well beyond the 1000-hour mark before capacitance loss hits the end-of-life threshold.
Active lifecycle — current-production sourcing
Tolerance is -10% / +30%, which is typical for supercapacitors — the wide positive side accounts for the capacitance increase as the carbon electrode ages. The bulk package means it ships loose in a tube or tray, not taped-and-reeled, so plan for hand-placement or tube-fed pick-and-place if your line handles radial cans.
