3. I
rms
: DC current for an approximate temperature rise of 30 °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.
4. I
sat
: Peak current for approximately 20% rolloff @ +25 °C
5. K-factor: Used to determine B
p-p
for core loss (see graph). Bp-p = K * L *
ΔI.
B

: (Gauss), K: (K-factor from table),
L: (Inductance in μH),
ΔI
(Peak to peak ripple current in Amps).
6. Part Number Definition: HCM1A1104-xxx-R
HCM1A1104 = 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: 1AXXX=automotive grade, 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
Tolerances are ±0.3 millimeters unless stated otherwise
DCR measured from point “a” to point “b”
Color: Grey
Do not route traces or vias underneath the inductor
