470 mF energy reserve for 5 V hold-up circuits
The SCMR14C474PRBA0 is a 470 mF supercapacitor from KYOCERA AVX's SCM series, rated at 5 V with a 300 mOhm ESR at 1 kHz. This capacitance and voltage combination makes it suitable for short-duration backup power, peak-power buffering, and ride-through applications where a battery would be oversized or have cycle-life limitations. The 300 mOhm ESR determines the charge and discharge efficiency — a lower ESR means less internal heating during high-current pulses, which matters when the supercapacitor is cycled frequently in a power-buffer role. The 5 V rating aligns with common 5 V logic and supply rails, though derating to 4.5 V or lower extends operational life.
Through-hole radial can with PC pin termination
The through-hole mounting suits wave-solder assembly and manual prototyping; the 0.453-inch (11.50 mm) lead spacing matches standard 0.2-inch grid prototyping boards. The bulk packaging means parts are shipped in tubes or trays rather than tape-and-reel, which is typical for through-hole components. For low-to-medium volume builds or lab prototypes, bulk packaging avoids the minimum quantity constraints of reel packaging.
Temperature range and lifetime at rated conditions
The 1000-hour lifetime at 65°C is the endurance specification under continuous rated voltage and temperature — at lower temperatures or with voltage derating, the operational life extends significantly. The 0%, +100% tolerance on capacitance means the actual capacitance can range from 470 mF to 940 mF. This wide tolerance is typical for supercapacitors and must be accounted for in timing or energy-budget calculations — design the hold-up time for the minimum capacitance, not the nominal value.
The part carries no known compliance restrictions — standard RoHS and REACH documentation is available from the manufacturer.
