NOTES:

1. Inductance measured at 100kHz, 100mVrms.

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.

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 heat-

ing current depending on which value is lower.

4. The nominal DCR is measured from point

mechanical drawing.

① to point ②, as shown below on the

8. Parts with the HLT suﬃx are sold in tape and reel packaging. Pulse complies to

industry standard tape and reel speciﬁcation EIA-481.

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.

The tape and reel for this product has a width (W=24mm), pitch (Po=16mm) and

depth (Ko=10.5mm). Samples of these parts can be ordered by removing the HLT

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 40°C when used in a typical application. the stated operating temperature range.
