Coin Cell Electric Supercapacitors Provide Memory Backup



Liberty, SC – The new EDC and EDS series of Coin Cell style EDLC capacitors from Cornell Dubilier (CDE) can replace or extend battery life in on-board memory backup. With quick-response and recharge times, these devices offer higher power than batteries and greater energy than typical aluminum electrolytic capacitors without degradation over millions of charge-discharge cycles.

Both series offer values from 0.047 to 1.5 Farad capacity, at voltages up to 6.3 WVDC for the EDC series; and 5.5 WVDC for the EDS series. Operating temperature for the EDS series is from -25 °C to +85 °C, with the EDC series offering -25 °C to +70 °C.  Three case configurations are available for horizontal, vertical and radial-lead PCB mounting. 

EDC and EDS series capacitors are ready to board mount in such applications as real-time clock (RTC) backup, power failure backup, battery assist and in market segments such as smart metering, HVAC controls, building automation, communication systems, appliances, instruments and other microprocessor-based devices.  Because of their high volumetric power density, they can be an effective way to reduce board size and weight.  Either series can be used as a drop-in replacement for similar value capacitors recently discontinued by other manufacturers. Lead times are less than 12 weeks with popular values in stock.

CDE’s Coin Cell style Supercapacitors are available now from the company’s franchised distributors. For more information on this series visit:
