350F Supercaps offer Low ESR and Low CostJuly 11, 2017 by Paul Shepard
The newest series of super capacitors from Illinois Capacitor is the DGH Series, offering capacitance values up to 350 Farads. This series continues a supercapacitor trend of incremental improvements, while achieving lower costs. The DGH Series includes 21 different value/voltage combinations, ranging in capacitance from 0.5F to 350F, with voltage ratings from 2.7 to 5.5wVdc. ESR varies by part, but is notably lower than capacitors with similar storage capabilities. Operating temperature ranges from -40 to +65 degrees C for extended life performance in countless applications.
Like other IC super capacitors, DGH supercaps provide engineers with interesting new design options. With their massive energy storage, they have the ability to provide instantaneous bursts of power to smooth power interruptions, supplement batteries or even be used in place of batteries in certain applications. DGH supercaps do not degrade with each cycle. At 2.7 Volts, operating life is rated at 10 years with 500,000 cycles.
Applications for these super capacitors include: energy harvesting, mechanical actuators, transportation power, smart electric meters, pulse battery pack alternatives, memory backup, battery/capacitor hybrids, UPS systems, emergency lighting, LED power, solar lighting or anywhere that significant energy storage is needed.
DGH Series capacitors are offered with radial wire leads or snap mounts. Case diameters and configurations vary, depending on values. The parts are also fully RoHS compliant. Prices start at about $0.20 for a 1 Farad at 2.7 Volt. Delivery: stock to 45 days for production quantities. Custom modules, with active or passive balancing, are also available, combining multiple capacitors for higher voltage or capacitance specifications.
