The SCMR22G105SRBA0 is a 1 F supercapacitor rated at 7.5 V with an ESR of 180 mOhm at 1 kHz. The 1 F capacitance provides enough energy storage for a backup hold-up or peak-power buffer in a low-voltage rail, while the 7.5 V rating covers a 5 V rail with margin and can stack two in series for a 15 V bank. The 180 mOhm ESR limits the peak discharge current — at 7.5 V the theoretical short-circuit current is about 42 A, but the real pulse current is constrained by the cell's internal resistance and the circuit's series impedance. For a 1 A pulse, the voltage drop across the ESR is 180 mV, which is acceptable for most hold-up applications.
Radial through-hole package — board-fit and integration
The 0.531-inch (13.50 mm) lead spacing matches standard 0.5-inch or 13.5 mm pitch on a perfboard or PCB layout. PC pin termination — solder into plated through-holes; no special connector needed. Lifetime is rated 1000 hours at 65°C — at lower temperatures the expected life increases roughly by a factor of 2 for every 10°C drop below the rated temperature.
