2I
rms
: DC current for an approximate ΔT 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 the part
temperature not exceed 125°C under worst case operating conditions verified in the end
application.

5 Part Number Definition: HCP0703-xxx-R
• HCP0703 = 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
