EC Geometry

The chart below shows the various power capabilities
of each size EC core with a given topology and frequency.
All numbers shown are in Watts and reflect typical power materials
used by Rhombus Industries with core loss at
100 mW/cm3 for a 250C temperature rise
All numbers rounded down to lowest whole number.
