("CAP-XX" or the "Company")

Launch of 3V product targeting coin cell battery and IoT markets

CAP-XX Limited, a world leader in the design and manufacture of supercapacitors and energy management systems, announces the launch of 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.

The 3V prismatic supercapacitor can complement 3V coin cell primary batteries, replace bulky 3V cylindrical supercapacitors in space-constrained devices, or enable battery-less energy storage using energy harvesting. Potential applications include battery-less remote wireless sensors, wireless HVAC sensors and actuators, asset tracking and RTC and memory backup power. CAP-XX's 3V DMV750 provides 23% more energy than a 2.7-volt supercapacitor in the same size package, providing 750mF of capacitance and 10A high peak pulse power to enable battery-less, low-power applications. It measures 21 millimetres x 14 millimetres x 2.2 millimetres, and operates from -20°C to +85°C.

This new launch is part of CAP-XX's strategy of ongoing product development activities to address developments in the energy storage devices market. There are an estimated 5 billion 3V coin cell batteries and 12 billion IoT devices sold annually. While not all of these applications require a supercapacitor, a large number would benefit from using the new CAP-XX DMV750. As with all new electronic component products, this product will need to be designed into end products for volumes to ramp-up.

The first samples have already been shipped to select customers and the product is now available for purchase from the CAP-XX on-line website store.

Anthony Kongats, CEO of CAP-XX said:

"We are delighted to be launching this new ultra-thin prismatic 3V supercapacitor, which can advance electronics sustainability by enabling micro energy harvesting applications and eliminating batteries or can complement the ubiquitous 3V coin cell batteries, thereby dramatically extending the battery life and functionality of the coin cell."
