NOTES:
1. Actual temperature of the component during system operation (ambient plus temperature rise)
must be within the standard operating range.
2. The Saturation Current is the current at which the initial inductance drops approximately by
the value shown at the stated ambient temperature. This current is determined by placing the
component in the specified ambient environment and applying a short duration pulse current
(to eliminate self-heating effect) to the component.
3. The Rated Current the value shown is the DC current required to raise the component tempera-
ture by the value shown. Take note that the component’s performance varies depending on the
system condition. It is suggested that the component be tested at the system level, to verify the
temperature rise of the component during system operation.
4. The inductance tolerance of the .152NLT and .332NLT is ± 30% all other values are ±20%.
