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.

The KW Series offers a wide range of high capacitance coin cell style products

for use in memory and RTC back-up applications. End products include

electricity meters, motor control units and solar inverters.
