1. The temperature of the component (ambient plus temperature rise)
must be within the specified operating temperature range.
2. Inductance at Irated is a typical inductance value for the component
taken at rated current.
3. The rated current listed is the lower of the saturation current @ 25°C
or the heating current.
4. The inductance at Bias is the controlled inductance value measured
after subjecting the part to the listed dc bias current.
5. The saturation current, I
SAT
, is the current at which the component
inductance drops by 20% (typical) 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.
6. 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. The temperature is measured by placing the
thermocouple on top of the unit under test. 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.
7. Core loss approximation is based on published core data:
Core Loss
= K1 * (f)
1.48
* (K2ΔI)

8. Unless otherwise specified, all testing is made at 100kHz, 0.1V

.
9. Optional Tape & Reel packaging can be ordered by adding a "T" suffix to
the part number (i.e. PG0255.601NL becomes PG0255.601NLT). Pulse
complies to industry standard tape and reel specification EIA481.
