165 F module at 48 V — the energy buffer for high-power hold-up
The KYOCERA AVX SCMZ1EP167SRBB0 is a 165 F supercapacitor module rated at 48 V, part of the SCM series. The 5.22 mOhm ESR at 1 kHz means this module can deliver high peak currents without significant internal voltage drop — the limiting factor in hold-up time calculations is the capacitance, not the series resistance. Rated for 1000 hours at 65 °C with an operating range of -40 °C to 65 °C, the lifetime is defined by the temperature exposure: every 10 °C drop below 65 °C roughly doubles the service life, so a 45 °C ambient pushes the expected life well beyond 4000 hours.
Module form factor and termination
Housed in a module measuring 415 mm x 190 mm x 180 mm, the SCMZ1EP167SRBB0 terminates with a cable and connector — no PCB footprint to design, just a bolt-down or bracket mount and a wire run to the bus. The user-defined mounting means the enclosure designer chooses the mechanical retention method. Tolerance is -10% / +30% on the 165 F nominal capacitance. At end of life the capacitance may drift toward the lower bound, so the hold-up time budget should use the -10% figure as the minimum guaranteed value.
The cable-with-connector termination is fixed — verify the mating connector type before specifying.
