SCx Supercapacitors

KEMET SCx Supercapacitors offer ultra-low equivalent series resistance (ESR), low leakage current, high cycle life, and radial lead or snap-in designs. The low ESR enables high power density and fast charge/discharge, while the robust environmental performance makes them resistant to humidity and vibration. These supercapacitors come in five series: SCS (high performance), SCC (high capacitance), SCT (high temperature), SCV (high voltage), and SCE (low ESR). KEMET SCx Supercapacitors are suitable for energy storage, backup power, and power assist applications.
