CAP-XX has developed an ultra-thin 3-V prismatic supercapacitor, targeting IoT, medical and other space-constrained and mission-critical electronic devices. The new 3.3-V DMV750 offers 23% more energy than a 2.7-V supercap in the same size package.

Other features include a capacitance of 750 mF, an equivalent series resistance (ESR) of 150 mW, and an operating temperature range from -20°C to 85°C. The device is housed in a 21 × 14 × 2.2-mm package.
“Supercapacitors handle peak power events, supporting batteries and energy harvesters configured to provide low-power current at maximum efficiency,” said CAP-XX. “This allows designers to use smaller, cheaper, low-power batteries and extend their run-time and cycle life, or use intermittent ambient energy sources like solar photovoltaic.”
The multi-purpose DMV750 supercapacitor provides high peak pulse power to enable either batteryless or more battery-efficient applications. The super cap can support the popular 3-V coin cell battery to extend its life and functionality or replace a larger 3-V cylindrical supercapacitor to save design space. It also can replace batteries by using energy harvesting (such as from solar, vibration and RF) to charge the supercapacitor in batteryless devices, said the company.
Key applications include energy harvesting for remote wireless sensors, wireless HVAC sensors and actuators; RTC and memory backup power; peak load shaving when configured in parallel with a 3-V coin cell battery and asset tracking.
Samples are available. Prices range from $4.95 to $15, depending on the quantity.
