Please specify **termination** and **packaging** codes: ## **MSS1038T-105KLC** **Termination: L** = RoHS compliant matte tin over nickel over copper. **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 (250 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 (1000 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4263B LCR meter or equivalent. 3. SRF measured using an Agilent/HP 8753D or equivalent. 4. DC current at which the inductance drops the specified amount from its value without current. 5. Current that causes the specified temperature rise from 25°C ambient. 6. Electrical specifications at 25°C. - Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
