1. When ordering, please specify **termination** and **packaging** codes: | ~~———_~~ **0402DF-771XJRW**
- **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).
- **U** = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter W instead.
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.
