This value represents the applied V-S at 200kHz necessary to generate a core loss equal to 10% of the total losses for 40C temperature rise. See Core Loss Graph. 2) Irms Amps for approximately T of 40C. DC current for an approximate T of 40C without core loss. Derating is necessary for AC currents. It is recommended that the temperature of the part not exceed 125C under worst case operating conditions verified in the end application.
