PowerStor® KW Series
Coin Cell Supercapacitors

PowerStor® KW Series Coin Cell Supercapacitors offer the smallest available package size and lowest ESR in a full -40ºC - +85ºC operating temperature range. The KW Series Coin Cell Supercapacitors from Cooper Bussmann also have an excellent operating life of 1000 hours at 85ºC and are ideal for high reliability industrial applications by providing a full industrial temperature range for low current RTC & memory back-up requirements and a demonstrated 20-year operating life. KW Series Supercapacitors have a low-profile design that makes them very useful in space constrained applications.  KW Series specifications include capacitance from 0.1F to 1.0F and 5.5 voltage.
