heating current depending on which value is lower.
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.
ature of the part to increase by approximately 40°C. This cur-
rent is determined by mounting the component on a PCB with
.25" wide, 2 oz. equivalent copper traces, and applying the cur-
rent to the device for 30 minutes. In the series hookup mode,
the resistance of the interconnection needs to be taken into
account when calculating temperature rise.
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.

Estimated Temperature Rise:
number (i.e. PA0135.102 becomes PA0135.102NL and
PA0135.102T becomes PA0135.102NLT).
The temperature of the component (ambient temperature +
temperature rise) should be within the listed operating
temperature range.
