Document 335-1 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. RVAR = k * • k is shown for each value in the accompanying table. Pad Air gap Pad • f is the frequency in Hz Brass ground plane Calibration plane 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:// www.coilcraft.com/models.cfm.
