inductance to drop by 10% at the stated ambient temperatures
(-40°C, 25°C, 125°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.

current is determined by mounting the component on a PCB
with .25" wide, 3 oz. equivalent copper traces, and applying the
current to the device for 30 minutes.
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. In order to determine
the approximate total losses (or temperature rise) for a given
application both copper losses and core losses should be taken
into account.

becomes PA0277NLT).
Estimated Temperature Rise:
The temperature of the component (ambient temperature +
temperature rise) should be within the listed operating
temperature range.
