Specify **termination** and **packaging** codes: **MSS1210-106KED** - **Termination: E** = RoHS compliant matte tin over nickel over phos bronze. - Special order: - **Q** = RoHS tin-silver-copper (95.5/4/0.5) or **P** = nonRoHS tin-lead (63/37). - **Packaging: D** = 13″ machine-ready reel. EIA-481 embossed plastic tape (300 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 D. 2. Inductance tested at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/ HP 4263B LCR meter or equivalent. 3. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture. 4. SRF measured using Agilent/HP 4191A or equivalent. 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.
