: 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.

- HCM1707 = Product code and siz
yyy= Inductance value in uH, R = decimal point
if no R is present then third character = number of zeros.
- “-R” suffix = RoHS compliant
: Peak current for approximately 20% rolloff at +25 °C.
