5 F, 6 V — energy buffer for hold-up and peak-power backup
The KYOCERA AVX SCMS32H505PRBB0 is a 5 F supercapacitor from the SCM series, rated at 6 V with a maximum ESR of 120 mOhm at 1 kHz. That ESR figure governs how fast the cell can deliver its stored energy — a lower ESR means less voltage sag under pulsed loads, which matters when this cap is backing up a real-time clock or bridging a power gap during a supply dropout. The 5 F capacitance at 6 V gives an energy storage of roughly 90 J (½CV²). In practice, that translates to several seconds of hold-up time for a microcontroller or SRAM bank drawing tens of milliamps, making it a fit for ride-through in industrial controllers, metering, and telemetry gear where a battery is undesirable.
Through-hole radial can — board-fit and thermal budget
Packaged in a radial can with PC pins and a lead spacing of 0.610" (15.50 mm), the SCMS32H505PRBB0 mounts through-hole on a PCB. That endurance figure is the baseline under full rated voltage and temperature; derating the voltage or operating below 65°C extends the service life significantly, which is the typical deployment in indoor or sheltered enclosures where ambient stays below 50°C.
For BOM planning, the 0%, +100% tolerance on capacitance means the actual value can range from 5 F up to 10 F — the wide upper tolerance is typical for supercapacitors and must be accounted for in the charge-circuit design and hold-up time calculation. The bulk package ships as loose parts, not tape-and-reel, so pick-and-place requires a tube or tray feeder.
