NOTES:
1. Actual temperature of the component during system operation (ambient plus temperature 3. The Rated Current is the DC current required to raise the component temperature by approxi-
rise) must be within the standard operating range.
mately the value listed. 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.
±. The Saturation Current is the current at which the initial inductance drops approximately 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.
4. Please note that the inductance tolerance is ±±20 for all parts except PA4319.33±ꢀNT(±320)
and PA4319.684ꢀNT (±120).
