Our 0403HQ Series ceramic chip inductors were designed for very high Q applications in a small size. They feature excellent current handling – up to 2.2 Amps and provide inductance values not available in other series of similar size.

Very high Q - up to 96 at 1.7 GHz!
11 inductance values from 1.9 to 18 nH
Excellent current handling - up to 2.2 Arms
Provides intermediate inductance values not available in other series
AEC-Q200 Grade 1 (−40°C to +125°C)

Notes

When ordering, please specify termination and packaging codes: e.g. 0403HQ-18NXJEW
Inductance measured at 500 MHz using a Coilcraft SMD-F fixture in an Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation pieces.
Q measured at 500 MHz using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
SRF measured using an Agilent/HP 8722ES network analyzer and a test fixture with a 0.017" air gap. Details
DCR measured at 25°C on a micro-ohmmeter and a Coilcraft CCF858 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
Irms: Current that causes a 30°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

E = Halogen free component. RoHS compliant. Silver-palladium-platinum-glass frit terminations.
L = RoHS compliant, not halogen-free. Silver-palladium-platinum-glass frit.
T = RoHS tin-silver-copper (95.5/4/0.5) (Special order, added cost)
S = non-RoHS tin-lead (63/37) (Special order, added cost)

Packaging:

W = 7″ machine-ready reel. EIA-481 punched paper tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
U = 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 U to W.
