Coin cell supercapacitors for real-time clock (RTC) backup

Eaton coin cell supercapacitors are ideal for providing backup power for real-time clocks, volatile memory, and other applications. Eaton KR supercapacitors are rated at 5.5 volts and offered with capacitance values from 0.1 to 1.5 Farads and an operating temperature range up to 70 degrees Celsius.  KW supercapacitors extend the operating temperature to 85 degrees Celsius with capacitance values up to 1 Farad at 5.5 volts.  Both offer low leakage current and a lifetime of 20 years. KVR and KVW supercapacitors are similar to the KR and KW families, but with a voltage rating of 5 volts and fewer capacitance values.  All Eaton coin cell supercapacitors offer high energy density in small diameter and low-profile packages. The higher voltage rating of the KR and KW make them ideal for industrial, energy, and computing applications, while the KVR and KVW are suitable for lighter industrial and consumer applications.
