CDE Coin Cell Supercapacitors Provide Memory Backup in Circuits up to 6.3V

11.9.2019
Reading Time: 1 min read

Source: Cornell Dubilier news

The 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.

Vishay Releases Automotive TO-220 Case 50W Thick Film Power Resistor

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.

Highlights

  • Long life
  • High discharge current
  • -70 ºC  (EDC) or -85 ºC (EDS) Operating temperature

Applications Include:

  • On-board memory backup circuits
  • Audio output circuits
  • Energy/Lighting
  • Smart utility meters (AMR)
  • Solar lights and energy storage
  • Power conversion
  • IoT–Energy harvesting/storage
  • Industrial controls
  • Telematics
