Peak current, Isat, is the current that result in 30% saturation of the core, assumes that equal current flows in all six winding. RMS current, Irms, will result in a surface temperature of approximately 40C above ambient when it flows through each of the six winding. Maximum energy capacity of each winding is based on 30% saturation of the core. Thermal resistance is the approximate surface temperature rise per Watt of heat loss under still-air conditions, assumes the underlying PCB copper area equals 150% of the component area. The internal "hot spot" temperature defines the maximum allowable currents, which are limited to 130C, including ambient.
