When ordering, specify tolerance, termination and packaging codes: 1111SQ-47NJEC Tolerance: G = 2% J = 5% (Table shows stock tolerances in bold.) Termination: E = RoHS compliant tin-silver (96.5/3.5) over copper. Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper. Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ( 25 charge). D = 13 machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel). Factory order only, not stocked. B = 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 B to C. 2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft CCF1191C test fixture. 3. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer or equivalent. 4. SRF measured using an Agilent/HP 8753 network analyzer or equivalent with a Coilcraft CCF1248 test fixture. 5. Current that causes a 20C temperature rise from 25C ambient. This information is for reference only and does not represent absolute maximum ratings 6. Electrical specifications at 25C. Refer to Doc 362 Soldering Surface Mount Components before soldering.
