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

2. Irms: DC current for an approximate DT 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 155°C

under worst case operating conditions verified in the end application.

3. Peak current for approximately 15% rolloff @+20°C

4. Peak current for approximately 30% rolloff @+20°C

5. Applied Volt-Time product (V-μs) across the inductor. This value represents the applied V-μs at operating

frequency necessary to generate additional core loss which contributes to the 40°C temperature rise.

De-rating of the I

equivalent to a ripple current Ip-p of 20% of Isat (30% rolloff option).

6. Part number definition: HC8LP-XXX-R

HC8LP = Product code and size

XXX = Inductance value in uH. R = Decimal point. If no R is present then last character equals

number of zeros

-R suffix indicates RoHS compliant

Part marking: HC8LP= (Product code and size)-xxx=(inductance value in uH, R= decimal point. If no R is present then last character equals

number of zeros. wwlyly=date code, R=revision level

Tolerances are ±0.2 millimeters unless stated otherwise

All soldering surfaces to be coplanar within 0.1 millimeters

Do not route traces or vias underneath the inductor
