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: HCM1305-yyy-R

- HCM1305 = Product code and size

yyy= Inductance value in µH, R = decimal point,

if no R is present then third character = number of zeros.

“-R” suffix = RoHS compliant
