1. When ordering, please specify **termination** and **packaging** codes: | ~~——————_~~
**0805AF-103XJRC**
- **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: 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
2. Inductance measured at 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
3. SRF measured using Agilent/HP 8753D network analyzer with Coilcraft SMD-D test fixture.
4. DCR measured on Cambridge Technology Micro-ohmmeter.
