When ordering, specify tolerance, termination and packaging codes: 1812SMS-R12GLC Tolerance: G = 2% J = 5% Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper. Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: C = 7 machine-ready reel. EIA-481 embossed plastic tape, 500 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. Factory order only, not stocked, 2000 parts per full reel. 2. Inductance and Q tested on the Agilent/HP 4291A with the 16193 fixture and correlation. 3. Tolerances in bold are stocked for immediate shipment. 4. SRF tested on the Agilent/HP 8753D and the SMD-D test fixture. 5. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter. 6. Current that causes a 15C temperature rise from 25C ambient. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering.
