1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 V

2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 V

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 155 °C under worst case operating

conditions verified in the end application.

L: (Inductance in μH), ΔI (Peak to peak ripple current in Amps).

6. Part Number Definition: HCM1A1707-xxx-R

HCM1A1707 = Product code and size

xxx= inductance value in μH, R= decimal point,

If no R is present then last character equals number of zeros

-R suffix = RoHS compliant

Part marking: HCM1A1707, XXX=inductance value in uH, R=decimal point. If no R is present then last character equals number of zeros.

xxxx=Lot code

All soldering surfaces to be coplanar within 0.1 millimeters

DCR measured from point “a” to point “b”

Color: Grey

Do not route traces or vias underneath the inductor
