The CAP-XX range of cylindrical supercapacitors provides a cost-effective solution to solve the power performance limitations of low power batteries in a range of consumer and industrial applications.

They provide excellent pulse power handling characteristics resulting from the combination of very high capacitance and relatively low ESR.

When used in conjunction with a low power energy source such as an energy harvester and or low power battery, the CAP-XX Prismatic range of Supercapacitors enables extended backup time, longer battery life, and the provision of peak power as required.
