CAP-XX secures distribution agreement with Digi-Key

Full line of CAP-XX supercapacitors available from world leading electronic components distributor

Sydney, Australia - April 25, 2023 - CAP-XX Limited (LSE:CPX), the leading manufacturer of ultra-thin prismatic, cylindrical, and Lithium-Ion supercapacitors, announces that its full line of high-performance supercaps is now available from global authorized distributor Digi-Key.

Digi-Key now stocksCAP-XX's wide range of supercapacitors, includingsurface-mountable ultra-thin prismatics ranging from .035 to 2.4 farad, board-mountable small cylindricals ranging from 1 to 100 farad, screw terminal and weldable large cylindricals ranging from 650 to 5000 farad,and hybrid supercaps (Lithium-Ion capacitors).Digi-Key previously distributed Murata branded supercapacitors.

Digi-Key has annual sales of over US$5bn and is a key resource for design engineers, offering a range of some 15 million products, theworld's largest selection of electronic components, in stock and available for immediate shipment.

"As IoT devices proliferate, and the focus on clean energy expands, demand is growing for supercapacitors that can either support batteries reducing their size and cost, or replace batteries altogether, as manufacturers strive to incorporate more high-power functionality and reduce the environmental impact of disposable batteries," said Jeff Colton, EVP at CAP-XX. "Supercaps are often used to deliver the burst power needed for high-power functions such as data capture and data transmission."

Colton continued, "Working with Digi-Key, we look forward to meeting the demands of today's design engineers."
