Super capacitors lower ESR for power, energy storage

ILLINOIS CAPACITOR DGH Series super capacitors provide capacitance values up to 350 Farads. Product series includes 21 different value/voltage combinations, ranging in capacitance from 0.5F (Farad) to 350F, with voltage ratings from 2.7 to 5.5WVdc. ESR varies by part, but is notably lower than devices with similar storage capabilities. Operating temperature ranges from -40 to +65°C for extended life performance in many applications. At 2.7 volts, operating life is rated at 10 years with 500,000 cycles.   http://www.illinoiscapacitor.com
