3.0-V Supercapacitor for High-Power, High-Energy Applications

The new 3.0-volt XT supercapacitor that offers 15 percent higher energy density and 20 percent higher power density at a lower cost per watt-hour versus currently available supercapacitors. The new supercapacitor allows a reduced size and weight for high cell count designs.
XT supercapacitors are unique, ultra-high capacitance devices utilizing electrochemical double layer capacitor (EDLC) construction combined with new, high performance materials. This combination of advanced technologies allows Eaton to offer a wide variety of capacitor solutions tailored to specific applications that range from a few micro-amps use for several days to using several amps for just seconds.
