SPICE Model – 0201DS
This lumped-element (SPICE) model data simulates the
frequency-dependent behavior of Coilcraft RF surface
mount inductors within the frequency limits shown in the
accompanying table.
The equivalent lumped element model schematic is shown
below. The element values R1, R2, C, and L are listed
for each component value. The value of the frequencydependent variable resistor RVAR relates to the skin effect
and is calculated from:
Lumped Element Modeling Method
The measurements were made over a brass ground
plane with each component centered over an 0.010 inch
(0.254 mm) air gap, 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.

Figure 1. Test Setup
Each model should be analyzed only at the input and
output ports. Conclusions based on individual lumped
element values may be erroneous.
The data represents de-embedded measurements, as
described below. Effects due to different customer circuit
board traces, board materials, ground planes or interactions with other components are not included and can
have a significant effect when comparing the simulation
to measurements of the inductors using typical production verification instruments and fixtures.
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.
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 reactive elements of a circuit board or fixture will
effectively lower the circuit resonant frequency, especially
for very small inductance values.
The lumped element values were determined by matching 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 up to a frequency just above
the self-resonant frequency of the model.
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://
