, 0.0 Adc, +25°C.
2. Full Load Inductance (FLL) Test Parameters: 100 kHz, 0.25 V
rms
, I
sat
, @ +25 °C.
3. I
rms
: 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. I
sat
: Peak current for approximately 20% rolloff at +25 °C.
5. K-factor: Used to determine B
p-p
for core loss (see graph). Bp-p = K * L * ΔI. B
p-p
: (Gauss), K: (K-factor from table), L:
(Inductance in μH), ΔI (Peak to peak ripple current in Amps).
6. Part Number Definition: HCM0703-xxx-R
HCM0703 = 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.
wly=date code, R=revision level
All soldering surfaces to be coplanar within 0.10 millimeters
Tolerances are ±0.3 millimeters unless stated otherwise
