: DC current for an approximate temperature rise 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.

7 Part Number Definition:HCF1007-xxx-R
• HCF1007 = 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
