Notes:
1.
Actual temperature of the component during system operation (ambient plus temperature rise) must be
within the standard operating range.
2.
Inductance at Irated is a typical inductance value for the component taken at rated current.
3.
The rated current as listed is either the saturation current (@ 25°C) or the heating current depending on
which value is lower.
4.
The DCR of the part is measured at an ambient temperature of 20°C±3°C from point a to b as shown below
on the mechanical drawing.
5.
The saturation current, Isat, is the current at which the component inductance drop by 20% (typical) at an
ambient temperature. This current is determined by placing the component in the specified ambient envi-
ronment and applying a short duration pulse current (to eliminate self-heating effect) to the component.
6.
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.the components’ performance varies depending on the system condition. It is suggested

Core loss approximation is based on published core data (at 100°C):
Core Loss = K1 * (f)
1.378
* (K2*ΔI)
2.864
in mW
K1 = 1.01E-9
f = switching frequency in KHz
K1 & K2 = core loss factors
ΔI=
delta I across the component in Ampere
K2*ΔI=one half of the peak to peak flux density across the component in Gauss
Unless otherwise specified, all testing is made at 100kHz, 0.1Vac
Optional Tape & Reel packaging can be ordered by adding a “T” suffix to the part number (i.e. PG1083.682NL
becomes PG1083.682NLT). Pulse complies with industry standard tape and reel specification EIA481. The
tape and reel for this product has a width (W=44.0mm), pitch (Po=32.0mm). The depth (Ko) has two types:
1) 10.6 mm for parts with height of 10.6mm max, 120 pieces/reel; 2) 12.9mm for the parts of 12.5mm max,
100 pieces/reel.
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 gener-
ate additional losses and potential overheating. Please contact Pulse to discuss an alternative solution if
required.
