This lumped-element (SPICE) model data simulates the

frequency-dependent behavior of Coilcraft RF surface

mount inductors from 1 MHz to the upper frequency limit

shown in the accompanying table.

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 typical produc-

tion veriﬁcation instruments and ﬁxtures.

Figure 1.Test Setup

The lumped element values were determined by match-

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

behavior of the component up to a frequency just above

the self-resonant frequency of the model.

Each model should only be analyzed at the input and

output ports. Individual elements of the model are not

determined by parameter measurement. The elements

are determined by the overall performance of the lumped

element model compared to the measurements taken of

the component.

The lumped element models were used to generate

our 2-port S-parameters and therefore give identical

results.The S-parameters are available on our web site

at http://www.coilcraft.com/models.cfm.

Typically, the Self-Resonant Frequency (SRF) of the

component model will be higher than the measurement of

the component mounted on a circuit board. The parasitic

reactiveelementsofacircuitboardorﬁxturewilleffectively

lower the circuit resonant frequency, especially for very

small inductance values. Since data sheet speciﬁcations

are based on typical production measurements, and the

SPICE models are based on de-embedded measure-

ments as described below, the model results may be

different from the data sheet speciﬁcations.

Lumped Element Modeling Method

The measurements were made over a brass ground

plane with each component centered over an air gap,

as illustrated in Figure 1. The gap width for each size

component is given in Table 1.The test pads were 30 mil
