Chip Inductors– 0805HQ Series (2012)
The 0805HQ Series offers our highest Q factors in an
0805 form factor. In addition, current handling has been
improved with significantly lower DCR values.
Like all Coilcraft wire wound ceramic chip inductors, the
0805HQ Series provides exceptional SRFs, tight induc-
tance tolerance and batch consistency.
Inductance

2.5 @ 250 MHz
5.6 @ 250 MHz
6.2 @ 250 MHz
12 @ 250 MHz
16 @ 250 MHz
18 @ 250 MHz
20 @ 250 MHz
27 @ 250 MHz
30 @ 250 MHz
39 @ 250 MHz
48 @ 200 MHz
51 @ 200 MHz
For even higher Qs, consider our surface mount spring
inductors that combine the high Q of an air wound coil
with the convenience of automatic placement.

1. When ordering, specify
tolerance, termination
and
packaging
codes:
0805HQ-51NXJLC
Tolerance:
G
= 2%
J
= 5% (Table shows stock tolerances in bold.)
Termination: L
= RoHS compliant silver-palladium-platinum-glass frit.
Special order:
T
= RoHS tin-silver-copper (95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel).
B
= Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (7500 parts per
full reel).
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286 impedance analyzer with Coilcraft-provided correlation pieces.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
5. For SRF less than 6 GHz, measured using an Agilent/HP 8753D network
analyzer and a Coilcraft SMD-D test fixture. For SRF greater than 6 GHz,
measured using an Agilent/HP 8722ES network analyzer and a Coilcraft
SMD-D test fixture.
6. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF840 test fixture.
7. Current that causes a 15°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
