Description
Eaton 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
Eaton 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.
