SPICE Model – XFL4020

This lumped-element (SPICE) model data simulates

The value of the frequency-dependent variable resistor

R_VAR1is calculated from:

the frequency-dependent behavior of Coilcraft power

inductors within the frequency range shown in the ac-

companying table for each individual inductor.

R_VAR1= k1

The data represents de-embedded measurements, as

described below.Effects due to different customer circuit

board traces, board materials, ground planes or interac-

tions with other components are not included and can

have a signiﬁcant effect when comparing the simulation

to measurements of the inductors using other production

veriﬁcation instruments and ﬁxtures.

Lumped Element Modeling Method

•ꢀ fꢀisꢀtheꢀfrequencyꢀinꢀHz

Measurements were made using a 50 Ohm impedance

analyzer.Fixturecompensationwasperformedtoremove

ﬁxture effects. No DC bias current was applied in any of

the measurements. The lumped element values were

determined by optimizing the simulation model to an

average of the measurements. This method results in a

model that represents as closely as possible the typical

frequency-dependent behavior of the component within

the model frequency range.

•ꢀ R_VAR2is the resistance in Ohms

Note: The log function in the following equation is the

natural logarithm, base e, not base 10.

The value of the frequency-dependent inductance L_VAR

is calculated from:

L_VAR= k3 − k4 * LOG (k5 f)

below. Each model should only be analyzed at the input

and output ports. Individual elements of the model are

not determined by parameter measurement. The ele-

ments are determined by the overall performance of the

lumped element model compared to the measurements

taken of the component.
