When ordering, please specify **termination** and **packaging** codes: | ~~——_!~~ **0402DF-332XJRW** - **Termination: R** = RoHS compliant matte tin over nickel over silverplatinum-glass frit. Special order: **Q** = RoHS tin-silver-copper (95.5/4/0.5) or **P** = non-RoHS tin-lead (63/37). - **Packaging: W** = 7″ machine-ready reel. EIA-481 punched paper tape (2000 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge). 2. Inductance measured at 7.9 MHz using a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces with an Agilent/HP 4286 impedance analyzer. 3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD -D test fixture. 4. DCR measured on Cambridge Technology micro-ohmmeter and a Coilcraft CCF858 test fixture. 5. Current that causes a 15°C temperature rise from 25°C ambient. Because of their open construction, these parts will not saturate. - Refer to Doc 362 “Soldering Surface Mount Components” before soldering. - **Y =** 7″ machine-ready reel. EIA-481 punched paper tape. Factory order only, not stocked (10000 parts per full reel). - **U** = 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 U to W.
