RF Toroid Calculator was developed to help users predict the RF characteristics of a ferrite or powdered-iron toroid wound as an inductor or suppressor.
It uses the manufacturer's (Fair-Rite & Micrometals) published data including the toroid's dimensions and complex permeability characteristics
to predict the component's characteristics.<br>
The calculator has 4 separate display areas. At the top is the chart display for showing frequency-dependent characteristics. Next is the
The calculator has 3 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 application type, toroid material, toroid size, wire size, number of windings and excitation voltage.<br><br>
