1 F at 8.1 V — where the voltage rating matters
The SCMR22J105SRBB0: The 1 F capacitance delivers enough energy storage for short-duration backup, peak-power assist, or ripple smoothing in applications like power-fail hold-up, meter logging, or actuator pre-charge.
ESR and lifetime — the real-world constraints
ESR is specified at 350 mOhm at 1 kHz — this sets the self-heating and voltage drop during charge/discharge pulses; a lower ESR would be preferred for high-current bursts, but this value is typical for a 1 F through-hole supercapacitor in this form factor. Lifetime is rated at 1000 hours at 65°C — the electrolyte aging accelerates with temperature, so operating at lower ambient (e.g., 40°C) will extend useful life well beyond the rated figure. Operating temperature spans -40°C to 65°C, covering most indoor and outdoor industrial enclosures but not extended high-heat environments like engine bays.
Through-hole radial can — board-fit checklist
Packaged in a radial can with PC pins on 13.50 mm lead spacing, the SCMR22J105SRBB0 mounts through-hole on a PCB — the 24.00 mm x 8.00 mm footprint and 23.50 mm seated height should be checked against enclosure clearance and adjacent component keep-outs. Supplied in Bulk packaging, suitable for hand-insertion or low-to-medium volume assembly; not tape-and-reel for automated pick-and-place.
