Total Power Dissipation (W) = CopperLoss + CoreLoss

CoreLoss = (from table)

Temp Rise vs Power Dissipation

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

formula can be used:

5. The temperature of the component (ambient plus temperature rise) must be within

the stated operating temperature range.

6. RoHS compliant version (100% pure Sn leads) available. Add suffix NL to the part

number.

D

B (Gauss) = K2 * DI

Notes

1. The rated current as listed is either the saturation current or the heating current

depending on which value is lower.

2. The saturation current is the typical current which causes the inductance to drop by

20% at the stated ambient temperatures (25°C and 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 heating current is the DC current which causes the part temperature

to increase by approximately 40°C.

4. In high volt*time applications, additional heating in the component can occur due
