Cornell Dubilier DGH Series of supercapacitors, available now from TTI Europe, has an attractive combination of low ESR and low cost.
The series includes 24 different value/voltage combinations, varying in capacitance from 0.5F to 600F, with voltage ratings from 2.7WVDC to 5.5WVDC. Operating temperature range of -40C to 65C at maximum WVDC, or from -40C to 85C at 2.3V. Multiple devices can be banked in parallel or series for yet higher voltage or capacitance. Due to their huge energy storage, the supercaps can discharge instantaneous bursts of power to smooth power interruptions, supplement batteries, or even be employed in place of batteries in certain applications. Unlike batteries, the devices do not degrade with each cycle.
Typical applications areas include energy harvesting, loT systems, mechanical actuators, transportation power, smart electric meters, memory backup, UPS systems, emergency lighting, LED power, and solar lighting.
