NOTES:
1. Inductance measured at 100kHz, 100mVrms.
2. Inductance at Irated is the value of the inductance at 25°C at the listed rated current.
3. The rated current as listed is either the saturation current (25°C or 100°C) or the heating current depending on
which value is lower.
4. The nominal DCR is measured from point a to point b , as shown below on the mechanical drawing.
7. In high volt*time applications, additional heating in the component can occur due to core losses in the inductor
which may neccessitate derating the current in order to limit the temperature rise of the component. To determine
the approximate total losses (or temperature rise) for a given application, the coreloss and temperature rise curves
can be used.
6. The heating current is the DC current which causes the part temperature to increase by approximately 40°C
when used in a typical application.

Mechanical
5. The saturation current is the typical current which causes the inductance to drop by 20% at the stated ambient
temperatures (25°C, 100°C ). This current is determined by placing the component in the specified ambient
environment and applying a short duration pulse current (to eliminate self-heating effects) to the component.
8. Parts with the HLT suffix are sold in tape and reel packaging. Pulse complies to industry standard tape and reel
specification EIA-481. The tape and reel for this product has a width (W=24mm), pitch (Po=16mm) and depth
(Ko=10.8mm). Samples of these parts can be ordered by removing the HLT suffix and replacing with HL.
9. The temperature of the component (ambient plus temperature rise) must be within the stated operating
temperature range.
