Introduction to Cable-Based Capacitors

The Cable-Based Capacitor (CBC) is Capacitech’s proprietary wire-shaped supercapacitor optimized for space to miniaturize electronics and complement batteries. The CBC’s unique form factor offers aesthetic and space saving advantages compared to existing supercapacitors on the market. 

The CBC is ideal for applications such as Internet of Things (IoT), wearables, emergency lighting, renewable energy systems, uninterruptible backup power supplies and energy harvesting. The CBC’s form factor allows it to be used where no supercapacitor has gone before, off the printed circuit board (PCB) and integrated into other parts of a product or system, such as inside a wiring harness. 

The CBC can also be installed on a PCB and routed through areas where space is available or bent to fit inside a small enclosure. The CBC’s high-power density can complement existing energy storage products and energy harvesting modules by providing peak-power support. Each CBC cell is rated to 1.6V (surge of 2V) and a capacitance of 3F. 

Individual units of the CBC can be connected in parallel or series to meet voltage and power requirements. While traditional supercapacitors are rigid and restricted to use on a PCB, the CBC is leveraging its flexible and wire-like form factor to build a discrete and distributed network of energy storage throughout the world’s infrastructure; inside of wiring harnesses, power cords, shoes and other wearables, electronics enclosures and more. 

The CBC technology gives design engineers more space, opportunity to add new features, and design flexibility to meet their customers’ needs by offsetting supercapacitors from the PCB or adding additional energy storage capability in parts of a product or system that was previously impossible.
