The SCMT32D755SRBB0 is a 7.5 F supercapacitor rated at 5.4 V continuous, part of the KYOCERA AVX SCM series. The 70 mOhm ESR at 1 kHz is the dominant term in the I²R heating budget during charge/discharge cycles — for a 1 A pulse, the internal temperature rise is roughly 70 mW per cell, which stays within the 1000-hour lifetime at 65°C rating as long as ambient stays below that ceiling. The -10%, +30% capacitance tolerance is typical for supercapacitors and must be factored into hold-up time calculations — design for the minimum 6.75 F to guarantee the backup duration, not the nominal 7.5 F.
Through-hole radial can — PCB footprint and mechanical fit
The PC pin termination is solderable in wave or selective-solder processes; the bulk packaging means individual tubes or trays, not tape-and-reel, so plan for manual or tube-fed insertion.
