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). B = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ( 25 charge), use code letter C instead. D = 13 machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel). Factory order only, not stocked. 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 CCF1143 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.
