(3) DC current (A) that will cause an approximate T of 40 °C. (4) DC current (A) that will cause L to drop approximately 20 %. 0 (5) The part temperature (ambient + temp rise) should not exceed 105 °C under worst case operating conditions. Circuit design, component placement, PWB trace size and thickness, airflow and other cooling provisions all affect the part temperature. Part temperature should be verified in the end application. (6) When tested using BQ Tesla 500110 Transmitter Chipset, BQ51013 Receiver Chipset and IWAS-4832FF-50 as receiver coil with 2.7 mm spacing. Testing performed per WPC guidelines.
