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)
S = Not RoHS Sn/Pb (63/37).
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (2000 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastictape. Factory order only, not stocked (7500 parts perfull reel).
B = 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 B to C.
2. Inductance measured at 2.5 MHz using Coilcraft SMD-A fixture inan Agilent/HP 4286A impedance analyzer with Coilcraft-provided
correlation pieces.
3. SRF measured using an Agilent/HP 8753D network analyzer with aCoilcraft SMD-D fixture.
4. DCR measured on a Cambridge Technology Micro-ohmmeter.
5. DC current at 25°C that causes an inductance drop of 10% (typ) from its
value without current.
6. Current that causes a 40°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute
maximum ratings.
7. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
