1. When ordering, specify tolerance, termination and packaging codes:
0603CT-56NXGRW
G = 2% J = 5%
(Table shows stock tolerances in bold.)
Termination: R = RoHS matte Sn over Ni over Ag-Pt-glass frit.
Special order:
T = RoHS Sn/Ag/Cu (95.5/4.0/0.5) (63/37).
S = Not RoHS Sn/Pb (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 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.
2. Inductance measured at 250 MHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A
fixture in Agilent/HP 4287A impedance analyzer.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured using Agilent/HP4291A with Agilent/HP 16193 test fixture.
