I : Heat rated current (I ) will cause the part temperature rise approximately T of 40 C. Circuit design, EXL1V0503 = Product code and size rms rms component, PCB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part xxx= inductance value in H, R= decimal point, temperature should be verified in the end application. The part temperature (ambient + temperature rise) should not If no R is present then third digit equals the number of zeros exceed +125 C under worst case operating conditions. -R suffix = RoHS compliant 6.
