1. When ordering, please specify **termination** and **packaging** codes: | ~~———_~~ **MSS7348-105MEC** 

- **Termination: E** = 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 (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. 

2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter. 

3. SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD -D test fixture. 

4. DC current at 25°C that causes the specified inductance drop from its value without current. 

5. Current that causes the specified 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. 

- **D** = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1000 parts per full reel).
