## 1. Please specify **termination** and **packaging** codes: 

## **MSS1048-334KLC** 

**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 tinlead (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 an Agilent/HP 4263B LCR meter or equivalent. 

3. SRF measured using an Agilent/HP 4192A impedance analyzer 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.
