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 approxi-
mately 30% at the stated ambient temperature. This current is determined by placing
the compnent in the specified ambient environment and applying a short duration
pulse current (to eliminate self-heating eect) to the component.
3. The rated current is the DC current required to raise the component temperature by
approximately 40�C. Take note that the components’ performanc 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 part temperature (ambient+temp rise) should not exceed 125�C under worst
case operating conditions. Circuit design, PCB trace size and thickness, airflow and
other cooling provisions all aect the part temperature. Part temperature should be
verified in the end application.
5. Please note that the inductance tolerance of all parts are ±20%, except .151NLT which
is ±30%.
6. Parts shown in bold are standard catalog parts and are available through sample
stock and distribution. Parts in lighter font are available but are not necessarily held
in sample stock or distribution and lead times may be longer. Please contact Pulse
for availablity.
