PowerStor® Supercapacitors

Eaton Electronics Supercapacitors provide high capacitance in smaller sizes and the lowest ESR values. Other features include high industrial temperature ranges, outstanding aging characteristics, high efficiency over the full product life, and a demonstrated operating life that exceeds 20 years. These capacitors also provide maximum energy savings and reduced running costs and eliminate the need for routine maintenance. PowerStor / Eaton Supercapacitors are used in alternate energy (solar and wind), medical (X-rays), computer (RAID storage and UPS), and industrial (elevators, forklifts, electric vehicles). They are available in cylindrical (HB, HV, and TV), snap-in cylindrical (XB,XV), and leaded cylindrical (PHB, PHV) types.
