Actual temperature of the component during system operation(ambient plus
temperature rise) must be within the standard operating range.
Inductance at Irated is a typical inductance value for the component taken at rated
current.
The rated current as listed is either the saturation current (@ 25°C) or the heating
current depending on which value is lower.
The DCR of the part is measured at an ambient temperature of 20°C±3°C from point a
and b as shown below on the mechanical drawing.
The saturation current, Isat, is the current at which the component inductance drop 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 effect) to the component.
The heating current, Idc, 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 components’ 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.

Core loss approximation is based on published core data:
Core Loss = K1 * (f)
1.324
* (ΔB)
2.422
in mW
K1 = 71.56 E-4
ΔB
= K2 * Vusec in mT
f = switching frequency in MHz
K1 & K2 = core loss factors
V = Voltage across the component in V
Vusec = V * D /f
D = Duty cycle
8. Unless otherwise specified, all testing is made at 100kHz, 0.1Vac
9. Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part
number (i.e. PG0871.222NL becomes PG0871.222NLT). Pulse complies to industry
standard tape and reel specification EIA481. The tape and reel for this product has a
width(W=16.0mm), pitch(Po=12.0mm) and depth (Ko=6.8 mm).
10. The core is a conductive material so care should be taken when mounting this
component over an exposed via or if the voltage across the terminals exceeds
24V. Trickle current through the core material may generate additional losses and
potential overheating. Please contact Pulse to discuss an alternative solution if
required.
