KW Coin Cell Supercapacitors

Eaton Electronics KW Coin Cell Supercapacitors feature the smallest available package size and lowest ESR in a full -40°C to +85°C operating temperature range. The series offers an operating life of 1000 hours at 85°C, 5.5V voltage, and a capacitance range of 0.1F to 1.0F. These supercapacitors are ideal for high-reliability industrial applications by providing a full industrial temperature range for low current RTC and memory backup requirements and a demonstrated 20-year operating life. The KW Coin Cell Supercapacitors have a low-profile design that makes them very useful in space-constrained applications.
