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
