## 1. Please specify **termination** and **packaging** codes:
## **MSS1246-105KLC**
- **Termination: L** = RoHS compliant matte tin over nickel over phos bronze. 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 (200 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 (800 parts per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD -A fixture in an Agilent/HP 4263B LCR meter or equivalent.
3. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test fixture.
5. DC current at which the inductance drops 10% (max) from its value without current.
6. Current that causes the specified temperature rise from 25°C ambient.
7. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
