SPICE Model – 0603AF

This lumped-element (SPICE) model data simulates the

frequency-dependent behavior of Coilcraft RF inductors

within the frequency range shown in the accompanying

table for each individual inductor.

VAR2

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.

VAR1

VAR

The value of the frequency-dependent variable resistor

R_VAR1is calculated from:

Lumped Element Modeling Method

Measurements were made using a 50 Ohm impedance

analyzer.Fixture compensation was performed to remove

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

the measurements.

Measurements were also taken on a network analyzer

over a brass ground plane with the component centered

over an air gap with a width of 0.026 inch (0.66 mm), as

illustrated in Figure 1.The test pads were 30 mil (50 Ohm)

wide traces of tinned gold over 25 mil thick alumina, and

were not included in the gap. The TRL* calibration plane

is also illustrated in Figure 1.

Disclaimer

Coilcraft makes every attempt to provide accurate mea-

surement data and software, representative of our com-

ponents, in a usable format.Coilcraft, however, disclaims

all warrants relating to the use of its data and software,

whether expressed or implied, including without limita-

and/or software.

The lumped element values were determined by optimiz-

ing the simulation model to an average of the measure-

ments.This method results in a model that represents as

closely as possible the typical frequency-dependent be-

havior of the component within the model frequency range.

The equivalent lumped element model schematic is

shown 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.
