Notes:

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 40°C 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 130°C,

including ambient.
