the heating current.
inductance drops by 20% (typical) at an ambient temperature of 25°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.
component temperature by approximately 40°C. The heating current is
determined by mounting the component on a typical PCB and applying
current for 30 minutes. The temperature is measured by placing the ther-
mocouple on top of the unit under test. 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.
