1. When ordering, please specify termination and packaging codes:
0403HQ-18NXJEW
Termination: E = Halogen free component. RoHS compliant silverpalladium-platinum-glass frit terminations.
L = RoHS compliant, not halogen-free. Silver-palladiumplatinum-glass frit terminations.			 Special order: T = RoHS tin-silver-copper (95.5/4/0.5)
or S = non-RoHS tin-lead (63/37).
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 withleader and trailer ($25 charge).
U = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from U to W.
2. Inductance measured at 500 MHz using a Coilcraft SMD-F fixture
in an Agilent/HP 4286 impedance analyzer with Coilcraft-provided
correlation pieces.
3. Q measured at 500 MHz using an Agilent/HP 4291A with an Agilent/
HP 16193 test fixture.
4. SRF measured using an Agilent/HP 8722ES network analyzer and atest fixture with a 0.017″ air gap.
5. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 testfixture.
6. Current that causes a 30°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolutemaximum ratings.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
