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 15°C temperature rise from 25°C ambient. Because of their open construction, these parts will not saturate. 7. Electrical specifications at 25°C.
