This Product Selection Guide contains information to help select products in the IC Batteries category on DigiKey.com
Products in this family are specialized modules containing an electrochemical power source used for powering real-time clocks in applications where tracking the passage of time in the absence of an external power source is needed. Typically designed for use with a specific time keeping integrated circuit, they provide a means of assembling temperature sensitive components onto a printed circuit board after the completion of other assembly processes involving high temperatures.
SelectionCharacteristics
Capacity: Describes energy storage capacity in terms of a product of output current and time duration, under manufacturer’s test conditions. Observed values will vary with application conditions.
Load Capacitance: The amount of external capacitance in parallel with a timing device that is required for specified operation.
Operating Temperature: Recommended operating temperature, typically given in a range or as a maximum. Exceeding these temperatures may affect performance or damage the device and other system components.
