Coin cell style electric double-layer supercapacitors provide memory backup in circuits up to 6.3 WV DC

07 November 2019

New Yorker Electronics has released a new EDC and EDS series of coin cell style EDLC capacitors from Cornell Dubilier (CDE). 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.

These new supercapacitors can replace or extend battery life in on-board memory backup. They are electric double-layer supercapacitors that provide high capacitance values in a thru-hole stacked coin type package.

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.

The CDE EDC series is rated at voltages up to 6.3 working voltage (WV) DC with an operating temperature of -25° C to 70° C. The EDS series is rated at 5.5 WV DC with an operating temperature of -25° C to 85° C. Both offer values from 0.047 F to 1.5 F capacity. Primarily designed for integrated circuit voltage backup, the capacitors can also be used to deliver the initial power from batteries.
