Notes
(1) All test data are referenced to 25°C ambient temperature
(2) Continuous operating temperature range must bewithin -40°C/+125°C (ambient + self heating) underworst case conditions;
exposure to 180°C peak is allowed. Thermal index H for all raw materials used
(3) Performances are subjected to change according to cooling capability of the cold plate where the component is "xed. It is
suggested to test the component at system level to verify its temperature rise after 30 minutes in the end application.
(4) Inductance values are measured at 10kHz/1V
(5) Hi-pot test between winding and between primary winding to core is above 5kV/50Hz/2sec
