G-serie Dual Cell Modules
ART.NR CAP-XX supercap G-serie

CAP-XX Supercapacitors G-series operate at 2.5V nom / 2.75V peak for a single cell and 5.0V nom / 5.5V peak for dual cell modules (2 cells connected in series). The operating temperature range for the G-series is -40°C to +70°C & Tmax = 70°C. CAP-XX Supercapacitors G-series include product references starting with CAP-XX GA, CAP-XX GS and CAP-XX GW.


  • Peak power for pulsed loads
  • Isolate the source from fluctuations in the load (input smoothing).
  • Extend battery life and run-time, especially when “old or cold”.
  • Enable the use of cheaper, smaller, lower power batteries.
  • Ride-through power for mission-critical applications
  • Isolate the load from fluctuations in the source (output smoothing).
  • Remove the need for back-up batteries and impact-resistant connectors.
  • Provide a low maintenance, uninterruptable on-board power supply.
  • Energy storage for energy harvesters and quick charge power supplies.
  • Environmentally friendly, low maintenance alternative to rechargeable batteries.
  • Efficient charging, with minimal losses, from variable / low power sources.
  • Ultra-quick charging via cable, cradle or induction to maximize operating time.


Cells or Modules:
Single cells, for ultra-thin designs & primary batteries/harvesters; or Dual cell modules, for rechargeable batteries & USB power supplies.

CAP-XX Supercapacitors G-series devices operate at 2.5V/cell (2.75V peak) and have an operating temperature range of -40°C to +70°C.
CAP-XX Supercapacitors H-series devices operate at 2.75V/cell (2.9V peak) and have a maximum operating temperature of +85°C. 

“S” = 39.0mm x 17.0mm
“W” = 28.5mm x 17.0mm
“A” = 20.0mm x 18.0mm
