<b><u>Notes:</u></b><br>
RF Toroid Calculator was developed to help users predict the RF characteristics of a ferrite toroid wound as an inductor.
Uses the manufacturer's (Fair-Rite) published data.<br><br>
It uses the manufacturer's (Fair-Rite) published data including the toroid's dimensions and complex permeability characteristics.<br><br>
The calculator has 4 separate display areas. At the top is the chart display for showing frequency-dependent characteristics. Next is the
schematic display, where a scaled image of the toroid and windings is presented to help with intuitive design. Next is the control panel
section, where the user can select the toroid material, toroid size, wire size, number of windings and excitation voltage.
<u>Inputs via the slider widgets:</u>
<ul>
<li>AWG : Select the wire gauge. Slider L-R changes AWG from 40-0.</li>
<li>N% : Selects the number of turns or windings. Maximum (100%) is reached when the wires are adjacent at the toroid's inner radius.</li>
<li>Vrms : The RMS voltage applied to the inductor (Volts). Determines the flux-density (B) and field-intensity (H) within the ferrite toroid.</li>
<li>f : Shifts the frequency of interest left-to-right. Left towards kHz, right towards GHz. </li>
<li>AWG : Select the wire gauge. Sliding L-R changes AWG from 40-0. (Defaults to 20 AWG)</li>
<li>N% : Selects the turns or winding density. Maximum (100%) is reached when the turns are adjacent at the toroid's inner radius. (Defaults to 20%)</li>
<li>Vrms : The RMS voltage applied to the inductor (Volts). Determines the flux-density (B) and field-intensity (H) within the ferrite toroid. (Defaults to 10Vrms)</li>
<li>f : Shifts the frequency of interest of the chart display from left-to-right. Left towards kHz, right towards GHz. </li>
</ul>
<p>Characteristics on the left are independent of frequency, while the characteristics on the right are dependent on the selected frequency. <br><br>
Each of the graphic representations attempt to keep the relative geometry correct, without exceeding the drawing boundary. The coil diameter
relative to the conductor diameter are representative. </p>
<u>Calculated dimensions:</u>
<u>Chart display:</u>
Calculated parameters are displayed against frequency (log scale). Each parameter may be displayed or hidden
by tapping on the legend key. Tapping on a data point will display the parameters for a single frequency.
<ul>
<li>&#8960;o : Outer loop diameter (inches) </li>
<li>&#8960;i : Inner loop diameter (inches) - corresponds to the diameter of the winding former.</li>
<li>c : Distance between windings, measured from the conductor centers (inches).</li>
<li>&#8467; : Length of the coil (inches). Equal to c x N.</li>
<li>|Z|(&#937;) : Impedance magnitude in Ohms. </li>
<li> R(&#937;) : Resistance due to core losses in Ohms. </li>
<li> X(&#937;) : Reactance in Ohms. </li>

<li>SRF : Self-resonant frequency (MHz) for the unloaded coil. Currently using a lumped reactances model. (Looking into modifying the model to
