Inductance measured at 100kHz, 100mVrms. 7. In high volt*time applications, additional heating in the component can occur due 2. Inductance at Irated is the value of the inductance at 25C at the listed rated current. to core losses in the inductor which may neccessitate derating the current in order 3. The rated current as listed is either the saturation current (25C or 100C) or the heat- to limit the temperature rise of the component. To determine the approximate total ing current depending on which value is lower. losses (or temperature rise) for a given application, the coreloss and temperature rise 4. The nominal DCR is measured from point to point , as shown below on the curves can be used. mechanical drawing. 8. Parts with the HLT suffix are sold in tape and reel packaging. Pulse complies to 5. The saturation current is the typical current which causes the inductance to drop by industry standard tape and reel specification EIA-481. 20% at the stated ambient temperatures (25C, 100C ). This current is determined by The tape and reel for this product has a width (W=24mm), pitch (Po=16mm) and placing the component in the specified ambient environment and applying a short depth (Ko=10.5mm). Samples of these parts can be ordered by removing the HLT duration pulse current (to eliminate self-heating effects) to the component. suffix and replacing with HL. 6. The heating current is the DC current which causes the part temperature to increase 9. The temperature of the component (ambient plus temperature rise) must be within by approximately 40C when used in a typical application. the stated operating temperature range.
