The Irated is either 85% of the Isaturation or the Iheating depending which is lower. 2. The Isaturation is the current which causes the inductance to drop by 15% of its nominal value. 3. The Iheating is the current which causes the temperature of the part to increase by approximately 45°C. Product performance is limited to specified parameters.
