Notes:
1.
2.
Actual temperature of the component during system operation (ambient plus
temperature rise) must be within the standard operating range.
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 compnent in the specified ambient environment and applying a short
duration pulse current (to eliminate self-heating effect) to the component.
The rated current is the DC current required to raise the component temperature by
approximately 40½C. 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 125½C 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.
Please note that the inductance tolerance is ±20% for all parts, except PA4546.101NLT
&PA4546.151NLT(±30%)
