1. Open Circuit Inductance (OCL) Test Parameters: 100 kHz, 0.25 Vrms, 0.0 Adc, +25 °C

2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 Vrms, Isat, +25 °C

3. Irms: DC current for an approximate temperature rise 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 125 °C under worst case operating

conditions verified in the end application.

4. Isat: Peak current for approximately 20% rolloff @ +25 °C

5. K-factor: Used to determine Bp-p for core loss (see graph). Bp-p = K * L * ΔI. Bp-p: (Gauss), K: (K-factor from table),

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

6. Part Number Definition: HCMA0503-xxx-R

HCMA0503 = 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: AXXX A=automotive, XXX=inductance value in uH, R= decimal point. If no R is present then last character equals number of zeros.

wly=date code, R=revision level

All soldering surfaces to be coplanar within 0.10 millimeters

Tolerances are ±0.2 millimeters unless stated otherwise

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

Color: Grey

Do not route traces or vias underneath the inductor
