7.5 F at 5 V — the energy buffer for a hold-up or peak-power gap
The SCMT32C755SRBA0 is a 7.5 F supercapacitor from the KYOCERA AVX SCM series, rated at 5 V with an ESR of 70 mOhm at 1 kHz. That combination of capacitance and low ESR means it can deliver a short burst of current — several amps for a few seconds — without dropping the output voltage below the downstream regulator's dropout threshold. The through-hole radial can with 0.709" (18.00 mm) lead spacing and PC pin termination fits standard PCB layouts for energy storage in backup power, peak-power assist, or ride-through applications. The 1000-hour lifetime at 65°C is typical for carbon-based supercapacitors; derating the voltage or reducing ambient temperature extends it significantly.
