: 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.

6. Part Number Definition: HCM1103-xxx-R
HCM1103 = Product code and size
xxx= Inductance value in µH, R = decimal point,
if no R is present then third character = number of zeros.
-R suffix = RoHS compliant
