1. When ordering, please specify termination and packaging codes:
0603AF-103XJRW
Termination: R = RoHS matte Sn over Ni over Ag-Pt-glass frit.			 Special order:
Q = RoHS Sn/Ag/Cu (95.5/4.0/0.5)
P = 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 withleader and trailer ($25 charge).
Y = 13″ machine-ready reel. EIA-481 punched paper
tape. Factory order only, not stocked (10000 parts
per full reel).
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 0.1 Vrms, using Coilcraft SMD-A fixture
in Agilent/HP 4286A impedance analyzer with Coilcraft-provided
correlation pieces.
3. Q measured on Agilent/HP 4395A with Agilent/HP 16193 test fixture.
4. SRF measured using Agilent/HP 8753D network analyzer withCoilcraft SMD‑D test fixture.
5. DCR measured on Cambridge Technology Micro-ohmmeter.
6. Current that causes a 15°C temperature rise from 25°C ambient.
Because of their open construction, these parts will not saturate. This
information is for reference only and does not represent absolutemaximum ratings.
7. Each part is marked with a single dot. The color dots are not unique
identifiers and correspond to multiple inductance values.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
