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.
The cylindrical line was developed to address a broader range of the market. Anthony Kongats, CAP-XX CEO, explained that customers had been asking for an alternative form factor at a lower price point.
Single-cell (2.7V) or dual-cell (5.4V) cylindrical supercapacitors deliver high peak pulse power and low ESR at a competitive cost, ranging from less than US$0.50 for the smallest devices (one to five Farads) to US$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 -40C to 65C. Assembly is by soldering or welding (ultrasonic, laser or spot), via radial lead, solder pin or tab.By comparison, CAP-XXs existing prismatic supercapacitors range from US$1.80 (1.0 millimeters thick, 180 milli-Farads, 40 milliohms) up to US$3.50 (3.5 millimeters thick, 1.2 Farads, 20milliohms) and are available in 2.5V / 70 C to 5.5V / 85 C configurations.
Supercapacitors can handle peak power events, supporting batteries and energy harvesters configured to provide low-power current at maximum efficiency. This architecture allows designers to use smaller, cheaper, low-power batteries and extend their run-time and cycle life, or use intermittent ambient energy sources such as solar photovoltaic. Supercapacitors also enable ultra-quick device charging and wireless power transfer, and provide the backup needed for graceful shutdown and last gasp transmissions in mission-critical applications.
