2I
rms
: DC current for an approximate ΔT of 40°C without core loss. Derating is necessary for AC
currents. PCB layout, trace thickness and width, air-flow, and proximity of other heat generating
components will affect the temperature rise. It is recommended that the temperature of the part
not exceed 125°C under worst case operating conditions verified in the end application.

= K*L*ΔI, B p-p(mT), K: (K factor from table), L: (Inductance in μH),
ΔI (Peak-to-peak ripple current in Amps).
