1. 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.
