1. Open Circuit Inductance (OCL) Test Parameters: 100kHz, 1.0Vrms, 0.0Adc, @ +25°C

2. Full Load Inductance (FLL) Test Parameters: 100kHz, 1.0Vrms, @ I

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.

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

6. Part Number Definition: HCM1307-xxx-R

HCM1307 = 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

Dimensions (mm)

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

wlyy=date code, R=revision level

All soldering surfaces to be coplanar within 0.10 millimeters

Tolerances are ±0.3 millimeters unless stated otherwise

Color: Grey

Do not route traces or vias underneath the inductor
