2. The saturation current is the typical current which causes the inductance to drop by 20% at 6. Add “T” suffix to the part number for Tape & Reel version (i.e. PA2050.582NLT).

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 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:
