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 ap-

proximately 30% at the stated ambient temperature. This current is determined by

placing the component in the specified ambient environment and applying a short

duration pulse current (to eliminate self-heating effect) 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 affect the part temperature. Part temperature should be

verified in the end application.

5.

Please note that the inductance tolerance is ±20% for all parts except PA4341.101NLT,

PA4341.151NLT, PA4341.161NLT, and PA4341.201NLT ‘s tolerance is ±30%.
