## 1. Please specify **termination** and **packaging** codes:
## **MSS7331-104MLC**
- **Termination: L** = RoHS compliant gold over nickel over phos bronze **Special order:**
- **T** = RoHS tin-silver-copper (95.5/4/0.5) over tin over nickel over phos bronze or
- **S** = non-RoHS tin-lead (63/37) over tin over nickel over phos bronze.
- **Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (350 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
- **D** = 13″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (1500 parts per full reel).
- **B** = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is eliminating the need for multiple packaging codes. When ordering, simply change the last letter of your part number from B to C.
2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/ HP 4284A LCR meter or equivalent.
3. For SRF >13 MHz, SRF measured using an Agilent/HP 8753D network Analyzer or equivalent. For SRF <13 MHz, SRF measured using an Agilent/HP 4192A or equivalent.
4. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information.
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. Click for temperature derating information.
