What the 5 F and 3 V rating mean for your hold-up circuit
The SCCR25E505PRB is a 5 F supercapacitor rated at 3 V from KYOCERA AVX's SCC series. That 5 F capacitance at 3 V stores enough energy to keep a real-time clock or SRAM alive through a brief power interrupt, or to deliver a short burst for a solenoid or actuator in a low-power system. The 85 mOhm ESR at 1 kHz means the internal resistance is low enough that the cap can source a few hundred milliamps without a major voltage drop — useful when the load pulls a pulse, not just a trickle. The -40°C to 65°C operating range covers most indoor and outdoor enclosures, though the 1000-hour lifetime at 60°C is a derating cue: keep the ambient below 50°C for multi-year service.
Through-hole radial can — board-fit and rework
The radial can measures 0.315 inches (8.00 mm) diameter and sits 1.063 inches (27.00 mm) tall when mounted. Lead spacing is 0.138 inches (3.50 mm), which matches the standard 3.5 mm pitch on many power-management boards. The PC pins are robust enough for hand-soldering or wave — the through-hole body is easy to extract with a desoldering iron if a replacement is needed, no hot-air risk. The bulk packaging means it ships loose in a bag or tube, not taped and reeled — fine for prototype builds or low-volume production, but if you need automated pick-and-place, you will want to confirm the feeder compatibility or order a reeled variant from the same SCC family.
