KW Series
Button cells with capacities from 0.1 to 1.5 F
The K-series from Powerstor are button cells for powering memories and Real Time Clock modules as a replacement for lithium button cell batteries. They have particularly low leakage currents. The standard series is the KR series with an operating temperature of -25...+70°C without derating, +85°C with derating to 3.6 V. The KW series reaches -40...85°C and has even lower leakage currents.
