Irms: DC current for an approximate temperature rise of 30 ºC without core loss. Derating is necessary for AC currents. (K-factor from table), L: (Inductance in μH), ΔI (Peak to peak ripple current in Amps).. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating components will affect the 5. Part Number Definition: DR1040-xxx-R temperature rise.
