Please specify **termination** and **packaging** codes: ## **ME3220-104KLC** - **Termination: L** = RoHS tin-silver-copper over tin over nickel over silver. Special order: - **S** = non-RoHS tin-lead (63/37). - **Packaging: C** = 7″ machine-ready reel. EIA-481 embossed plastic tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge). - **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. - **D** = 13″ machine-ready reel. EIA-481 embossed plastic tape (7000 parts per full reel). 2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in Agilent/HP 4284A impedance analyzer. 3. DCR measured on a micro-ohmmeter and Coilcraft CCF858 test fixture. 4. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD -D test fixture. 5. DC current at 25°C that causes the specified inductance drop from its value without current. Click for temperature derating information. 6. 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. 7. Electrical specifications at 25°C. - Refer to Doc 362 “Soldering Surface Mount Components” before soldering. **US** +1-847-639-6400 sales@coilcraft.com **UK** +44-1236-730595 sales@coilcraft-europe.com **Taiwan** +886-2-2264 3646 sales@coilcraft.com.tw **China** +86-21-6218 8074 sales@coilcraft.com.cn **Singapore** + 65-6484 8412 sales@coilcraft.com.sg ## Document 380-1 Revised 11/03/20 © Coilcraft Inc. 2020 This product may not be used in medical or high risk applications without prior Coilcraft approval.
