Supercapacitors

KEMET Supercapacitors are designed for high-energy storage applications and consist of four basic form factors: molded, chip, can, and radial through-hole. These superconductors offer rapid charging/discharging within seconds, open failure mode to eliminate short circuits, easy installation with automatic mounting, and pick-and-place capability. KEMET Supercapacitors approach infinite charge/discharge cycles with very little deterioration of capacitance or cycle life and are maintenance-free. Typical applications include a real-time clock, energy harvesting, test equipment, and industrial control.
