CAP-XX launches ultra-thin 3V, 750mF prismatic supercapacitor for space-constrained IoT and batteryless devices

The 3V ultra-thin prismatic supercap packs 23% more energy than a same-size 2.7V supercap, and can complement 3V coin cell batteries, replace bulky 3V cylindrical supercaps to save space, or replace batteries using energy harvesting to charge sustainable batteryless devices

Sydney, Australia – February 14, 2023 – CAP-XX (LSE:CPX), the leading manufacturer of ultra-thin prismatic, cylindrical, and Lithium-Ion supercapacitors, has launched its DMV750 ultra-thin 2.2mm prismatic 3V supercapacitor to provide high performance for IoT, medical and other space-constrained and mission-critical electronic devices.

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 millimetres x 14 millimetres x 2.2 millimetres, and operates from -20°C to +85°C.

“It is 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 will require a supercapacitor, a large number would benefit from using 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 (CR2032 for example)

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

About Supercapacitors:
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.
