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 milliamps
for milliseconds.
The PowerStor brand of
supercapacitors (formerly
of the Bussmann Division
of Cooper Industries)
is now part of
Eaton’s Electrical Group,
Electronics Division.
PowerStor is now
part of Eaton
Same great
products plus
even more.
