Notes from Tables

1. The rated current as listed is either the saturation current @ 25°C or the

heating current depending on which value is lower.

2. The saturation current Isat is the current which causes the inductance to

drop by 10% typical at an ambient temperature of 25°C. This current is

determined by placing the component in the specified ambient environ-

ment and applying a short duration pulse current (to eliminate self-heating

effects) to the component.

3. The heating current Idc is the dc current which causes the temperature

rise of the part to increase by approximately 40°C. This current is

determined by mounting the component on a typical application PCB and

applying the current to the device for 30 minutes.

4. Optional Tape and Reel packaging can be ordered by adding a "T" suffix

to the part number (i.e. PF0638.103NL becomes PF0638.103NLT). Pulse

complies to industry standard tape and reel specification EIA481.
