35 F supercapacitor for backup and peak-power hold-up
The KYOCERA AVX SCCU30E356SRB is a 35 F supercapacitor rated at 3 V, with a maximum ESR of 20 mOhm at 1 kHz. This combination of high capacitance and low ESR makes it suited for short-term energy storage applications such as power backup, peak-power buffering, and ride-through hold-up in embedded systems, where the capacitor supplies current when the main rail dips or drops out.
Radial can through-hole package and board integration
Housed in a radial can through-hole package with a 0.630-inch diameter and 1.260-inch seated height, the SCCU30E356SRB mounts directly to a PCB via 0.295-inch lead spacing and PC pin termination. The through-hole format provides robust mechanical anchoring for the 16 mm-diameter can, suitable for boards that undergo vibration or frequent handling during assembly.
Temperature range and lifetime profile
Rated for operation from -40°C to 65°C, the part covers indoor and sheltered outdoor environments. The lifetime specification of 1000 hours at 60°C means that continuous exposure near the upper temperature limit will accelerate aging; in typical room-temperature backup duty, the useful life extends well beyond the rated hours. The -10% to +30% capacitance tolerance accounts for initial spread and aging drift, so the minimum capacitance at end of life remains above the circuit's hold-up requirement.
