0604HQ (1610)

High Q Ceramic Chip Inductors

Our 0604HQ Series wirewound ceramic chip inductors are only slightly larger than the 0603 size, yet they have significantly higher Q factors – up to 178 at 1.7 GHz. The 0604HQ also has self-resonant frequencies up to 12.3 GHz and comes in values not covered by other 0603 series.

Exceptionally high Q – up to 178 at 1.7 GHz!
Inductance values from 1.15 to 10.4 nH
Very high self-resonant frequencies – up to 12.3 GHz

Notes

When ordering, please specify termination and packaging codes: 0604HQ-10NXJRC
Inductance measured at 500 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
Q measured at 500 MHz using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
For SRF >6 GHz, measured using an Agilent/HP 8722ES network analyzer and a Coilcraft SMD-D test fixture. For SRF <6 GHz, measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
DCR measured at 25°C on a Cambridge Technology Micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
Irms: Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
Each part is marked with a single dot. The color dots are not unique identifiers and correspond to multiple inductance values. Details.

Termination:

R = RoHS compliant. Matte Sn over Ni over Ag-Pt-glass frit terminations.

T = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (Special order, added cost)
S = Not RoHS Sn/Pb (63/37) (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
