Cylindrical Supercaps Address Space-Constrained Designs

13 March 2017

Cylindrical superconductors combine small size and low cost. Source-CAP-xx. Cylindrical superconductors combine small size and low cost. Source-CAP-xx. CAP-XX has launched its first compact cylindrical supercapacitors to provide high performance at low cost for less space-constrained devices. Combining its cylindrical supercapacitors with its existing thin prismatics that address ultra-space-constrained designs, CAP-XX now offers a wide range of small supercapacitors to power IoT industrial and consumer devices, from energy harvesting for wireless sensors to peak power support for wireless transmissions.

Single-cell (2.7 V) or dual-cell (5.4 V) cylindrical supercapacitors deliver high-peak pulse power and low ESR at a competitive cost, ranging from less than 50 cents for the smallest devices (one to five Farads) to $9 for the largest (400 Farads).

The smallest one Farad supercapacitor is 12 millimeters long and comes in two diameters: 6.3 millimeters (400 milliohms) and 8 millimeters (180 milliohms). The largest 400 Farad supercapacitor is 68 millimeters long and 35 millimeters in diameter (3 milliohms).

The temperature range is -40° C to +65° C. Assembly is by soldering or welding (ultrasonic, laser or spot), via radial lead, solder pin or tab.

Applications for the superconductors include:

  • Energy harvesting for wireless sensors, wireless HVAC sensors and actuators
  • Peak power support for GSM/GSR transmission, locks and actuators, and portable drug delivery systems
  • Last gasp power for remote meter status transmission
  • Short-term bridging power for battery hot swaps
