1. Inductance measured at 100kHz, 100mVrms.
2. Inductance at Irated is the value of the inductance at 25°C at the listed rated current.
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.
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 tem-
perature 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.
8. Parts with the HLT suffix are sold in tape and reel packaging. Pulse complies to industry
standard tape and reel specification EIA-481.
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.
4. The nominal DCR is measured from point
①
to point
②
, as shown below on the
mechanical drawing.

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.

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.
