T of 40°C without core loss. Derating is necessary for AC currents. PCB layout, trace thickness and width,
airflow, and proximity of other heat generating components will affect the temperature rise. It is recommended that the temperature of the
part not exceed 155°C under worst case operating conditions verified in the end application.
Operating ambient temperature range: -40°C to +155°C(Including self - temperature rise )
