Prior to use and for more details, refer to Introduction of the derating curves based on the terminal part temperature in the beginning of our catalog. Temperature rise at high power will depend on PCB layout. Be sure to contact factory prior to use and monitor terminal part temperature. environmental applications Performance Characteristics Requirement R (%+0.1 ) Parameter Limit Typical Test Method Resistance Within specified tolerance 25C T.C.R.
