CAP-XX launches 3V, 750mF prismatic supercapacitor

This multi-purpose 3V prismatic supercap can support the industry's common 3V coin cell battery to extend its life and functionality, replace a bulky 3V cylindrical supercap to save design space, or replace batteries altogether when micro energy harvesting can extract enough solar, vibration, RF or other environmental energy to charge the ultra-efficient supercapacitor in sustainable batteryless devices.

Packing 23% more energy than a 2.7-volt supercap in the same size package, the 3V, DMV750 supercap provides high peak pulse power to enable either batteryless or more battery-efficient applications. It measures 21 x 14 x 2.2 millimetres, operating from -20°C to +85°C.

"It's estimated that over 5 billion 3V coin cell batteries and 12 billion IoT devices are sold annually," explained Anthony Kongats, CEO at CAP-XX. "While not all devices require a supercapacitor, many would benefit from our powerful DMV750 supercapacitor to store and release the energy needed for peak power functions like data transmission."

3-Volt DMV750 applications include:

• Energy harvesting for remote wireless sensors, wireless HVAC sensors and actuators
• Asset tracking
• RTC and memory backup power
• Peak load shaving when configured in parallel with a 3V coin cell battery, like the CR2032

Kongats continued, "Our DMV750 ultra-thin 3V supercap provides engineers with multiple options to overcome power delivery challenges in space-constrained, mission-critical, sustainable electronic devices."

Samples are available for $4.95 - $15, depending on quantity ordered.

Supercapacitors handle peak power events, supporting batteries and energy harvesters configured to provide low-power current at maximum efficiency. 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.
