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. For even higher
Qs, consider our surface mount spring inductors that

These parts can be ordered with terminations that
make them compliant with RoHS standards.

(Table shows stock tolerances in bold.)
Termination: B
= Standard Ag/Pd/Pt
L
= RoHS compliant Ag/Pd/Pt
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).
Tolerance:
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/
HP 4286 impedance analyzer.
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. Average current for a 15°C rise above 25°C ambient.
8. Operating temperature range –40°C to +125°C.
9. Electrical specifications at 25°C.
