When ordering, please specify termination and packaging codes: 1812LS-105XJLC Termination: L = RoHS compliant silver-palladium-platinum-glass frit. 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 (600 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 (2200 per full reel). 2. Inductance at 2.5 MHz measured using an Agilent/HP 4286A and a Coilcraft SMD-A fixture with Coilcraft-provided correlation pieces. Inductance at 0.79 MHz measured using an Agilent/HP 4192A and Coilcraft SMD-B test fixture. 3. Q read at test frequency directly on an Agilent/HP 4192A LF impedance analyzer and a Coilcraft SMD-B test fixture. 4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 5. DCR measured on a Cambridge Technology micro-ohmmeter. 6. Current that causes a 15C temperature rise from 25C ambient. Because of their open construction, these parts will not saturate. 7. Electrical specifications at 25C. Refer to Doc 362 "Soldering Surface Mount Components" before soldering. See Color Coding section for part marking data. Specifications subject to change without notice.
