Cap-XX DMH 140mF Supercapacitors (DMHA14R5V353M4ATA0)

Product overview

CAP-XX DMH Supercapacitors (2.25V | 140mF)
2.25V, 140mF, 20 x 20 x 0.4 mm, -40 to 85°C, ESR 75mΩ

CAP-XX Murata DMH Supercapacitors 2.25V | 140mF (DMHA14R5V353M4ATA0) are low profile, low impedance (low ESR) power sources. Designed to overcome both the power delivery constraints of battery systems and the energy delivery limitations of conventional capacitors. CAP-XX Supercapacitors are the smallest devices available for given ESR and capacitance (high power and energy density).

These prismatic supercaps were previously made by Murata under license from CAP-XX. CAP-XX acquired the Murata supercap business and moved the highly automated production equipment from Japan to Australia. The supercaps are now made by CAP-XX in the CAP-XX factory near Sydney Australia.

CAP-XX Supercapacitors DMH – Key Features

  • High power output for peak current loads (low ESR)
  • Sufficient energy storage to handle power surges (high capacitance)
  • Wide operating temperature range (-40°C to +85°C)
  • Low leakage current
  • Meets environmental standards for disposal and operation RoHs

Typical Applications

  • Energy harvesting for wireless sensors & actuators
  • Peak power support for GSM/GPRS transmission
  • Last gasp power for remote sensor status transmission
  • Peak power support for locks and actuators
  • Peak power support for portable drug delivery systems
  • Short term bridging power for battery hot swaps
