The SCMR22F155PRBA0 is a 1.5 F supercapacitor rated at 5.5 V, from the KYOCERA AVX SCM series. The 200 mOhm ESR at 1 kHz sets the charge/discharge efficiency — a lower ESR means less internal heating during high-current pulses, which matters when the capacitor supplies a backup current spike or absorbs a regenerative burst. The 0%, +100% tolerance means the actual capacitance can be anywhere from 1.5 F to 3.0 F. For a hold-up time calculation, design for the minimum (1.5 F) to guarantee the backup duration; the higher side just extends the margin.
Through-hole radial can — PCB footprint and clearance
The through-hole radial can with PC pins and 0.453" (11.50 mm) lead spacing fits a standard 0.1" grid prototype board or a custom layout. The bulk package ships loose in a tube or tray, not tape-and-reel — plan for hand-insertion or a tube-fed through-hole machine. No moisture sensitivity level applies to this can construction.
Lifetime and temperature — the endurance envelope
Rated for 1000 hours at 65°C — this is the accelerated life test condition. At lower operating temperatures the lifetime extends significantly; at 40°C ambient the expected life roughly doubles for every 10°C drop below the rated temperature, per the Arrhenius model typical for electrolytic and supercapacitor technologies. Storage limits are wider but not specified here; the capacitor should be stored in a dry, non-condensing environment to avoid leakage current increase.
