Comparison Sheet

EDS/EDC Series Coin Cell Style Electric Double-Layer Supercapacitors

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.

Supercapacitors

KEMET offers a large range of supercapacitors in surface-mount and radial construction with high performance capabilities. Supercapacitors have characteristics that are common to both batteries and traditional capacitors. As a result, a supercapacitor can be used as a secondary battery when applied in a DC circuit. These devices are best suited for use in low voltage, DC hold-up applications such as embedded microprocessor systems with flash memory.
