Description

Cooper Bussmann^®PowerStor^®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 Cooper Bussmann

to offer a wide variety of capacitor solutions tailored to specific

applications that range from a few micro-amps for several days

to several amps for milliseconds.
