Characteristics

Characteristic	Description
Ambient Temperature	All test data is based on 25 ambient.
Temperature Rise	DC current(A) that will cause an approximate T40.
Operating Temperature Range	-40~+125.
Part Temperature Limit	The part temperature (ambient + temp rise) should not exceed 125 under worst case operating conditions. Circuit design, component, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the application.
