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.

ripple current in amps).

6. Part Number Definition: HCM1707-yyy-R

- HCM1707 = Product code and size

- yyy= Inductance value in uH, R = decimal point,

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

- “-R” suffix = RoHS compliant

All soldering surfaces coplanar within 0.10 millimeters.

Part marking: HCM1707; XXX = initial inductance in µH, R = decimal point;

if no R is present, last digit equals number of zeros.

wwllyy = date code, R = revision level

Color: Grey.
