The SCCS20E505PRB stores 5 F at a rated voltage of 3 V, which translates to 22.5 J of usable energy for short-duration backup or peak-power bridging in a 3 V rail. The 70 mOhm ESR at 1 kHz sets the internal resistance that governs how fast the cell can deliver that energy — a lower ESR means less voltage sag during a current pulse, so this cell suits applications like power-fail hold-up or real-time clock backup where the load draws a few hundred milliamps for a few seconds. The 0%, +100% tolerance on capacitance means a fresh part could measure anywhere from 5 F to 10 F. Design the discharge timing for the minimum capacitance and verify the circuit still holds the required voltage at the maximum — the wide tolerance is normal for supercapacitors and reflects the electrochemical double-layer construction.
Lifecycle and temperature limits
Rated for 1000 hours at 60 °C, which is the accelerated life test condition. At lower temperatures the lifetime extends — roughly doubling for every 10 °C drop below 60 °C, so at 45 °C the expected life is around 4000 hours. The operating range spans -40 °C to 65 °C, covering indoor and outdoor equipment in temperate climates, but sustained operation above 60 °C will shorten life per the Arrhenius model.
Board mounting and mechanical fit
Through-hole radial can with PC pin termination and 5.50 mm lead spacing. The can diameter is 10.00 mm and the seated height is 22.00 mm — this fits standard 10 mm diameter capacitor footprints on a PCB with 5.5 mm pitch holes. The bulk package means parts are shipped loose in a bag, not taped and reeled, so hand-insertion or tube-fed assembly is the typical process.
