: DC current for an approximate temperature rise of 40°C without core loss. Derating is

necessary for AC currents. PCB pad layout, trace thickness and width, air-flow and proximity of

other heat generating components will affect the temperature rise. It is recommended the part

temperature not exceed 125°C under worst case operating conditions verified in the end

application.

• SD3118 = Product code and size

• xxx= Inductance value in μH, R = decimal point.

If no “R” is present then third character =# of zeros

• -R suffix = RoHS compliant

: Peak current for approximately 30% rolloff at +20°C.
