Notes from Tables
1. Inductance at Irated is a typical inductance value for the compo-
nent taken at rated current.
2. The rated current listed is the lower of the saturation current @
25°C or the heating current.
3. The saturation current, Isat, is the current at which the
component inductance drops by 10% (maximum) 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.
4. The heating current, I
DC
, is the DC current required to raise
the component temperature by approximately 45°C. The heating
current is determined by mounting the component on a typical
PCB and applying current for 30 minutes.
5. Optional Tape & Reel packaging can be ordered by adding a "T"
suffix to the part number (i.e. PF0581.103NL becomes
PF0581.103NLT). Pulse complies to industry standard tape and
reel specification EIA481.
6. The temperature of the component (ambient plus temperature
rise) must be within the stated operating temperature range.
