Notes from Tables
1. Inductance at Irated is a typical inductance value measured when
the inductor is subjected to the 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 20% (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 40°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. PF0504.681NL becomes
PF0504.681NLT). 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.
