## 1. When ordering, please specify **termination** and **packaging** codes: | ~~——_~~ **DO3314-333MLC** 

**Termination:  L** =  RoHS compliant silver-palladium-platinum-glass frit 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 (1000 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 (3500 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. 

3. DCR measured on a micro-ohmmeter. 

4. SRF measured using Agilent/HP 4191A or equivalent. 

5. DC current at which the inductance drops 10% (typ) from its value without current. 

6. Current that causes a 40°C temperature rise from 25°C ambient. 

7. Electrical specifications at 25°C.
