When ordering, please specify **termination** and **packaging** codes: | ~~———_~~ **1812LS-105XJLC** - **Termination: L** = RoHS compliant silver-palladium-platinum-glass frit. - **R** = RoHS compliant matte tin over nickel over silverplatinum-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). 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. 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. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. 4. DCR measured on a Cambridge Technology micro-ohmmeter. 5. Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. 6. Electrical specifications at 25°C. - Refer to Doc 362 “Soldering Surface Mount Components” before soldering. Visit http://www.coilcraft.com/colrcode.cfm for part marking data. - **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. **US** +1-847-639-6400 sales@coilcraft.com **UK** +44-1236-730595 sales@coilcraft-europe.com **Taiwan** +886-2-2264 3646 sales@coilcraft.com.tw **China** +86-21-6218 8074 sales@coilcraft.com.cn **Singapore** + 65-6484 8412 sales@coilcraft.com.sg Document 1486-1 Revised 12/02/21 © Coilcraft Inc. 2021 This product may not be used in medical or high risk applications without prior Coilcraft approval.
