Document 197-1 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. 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. Like all Coilcraft wire wound ceramic chip inductors, the 0805HQ Series provides exceptional SRFs, tight inductance tolerance and batch consistency. Coilcraft Designer’s Kit C325 contains samples of all 5% inductance tolerance parts. To order, contact Coilcraft or visit http://order.coilcraft.com.

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.
