Coin Cell Style Electric DoubleLayer Supercapacitors Provide Memory Backup in Circuits up to 63 WVDCSeptember 09, 2019 by Cornell Dubilier
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.
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.
About Cornell Dubilier
A privately held, American owned company, Cornell Dubilier Electronics has earned a global reputation for manufacturing quality, high-end capacitors. Almost all of the company’s capacitors are used in demanding industrial applications, separating themselves from the competition. Cornell Dubilier’s roots can be traced back to 1909 when founder William Dubilier first used a glassy mineral called mica to help form a “condenser” (now called a “capacitor”). While the mica capacitor saw limited success for its intended application, it went on to revolutionize radio broadcast communications allowing for better transmission over longer distances.
