1. When ordering, specify **tolerance** , **termination** and **packaging** codes: 

**0402AF-561XJLW** 

**Tolerance: G** = 2% **H** = 3% **J** = 5% 

(Table shows stock values and tolerances in bold.) 

**Termination: L** = Gold over nickel over silver-palladium-glass frit. 

   - Special order: **T** = RoHS tin-silver-copper (95.5/4/0.5) or **S** = 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, 0.1 Vrms, using an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft SMD-F test fixture and Coilcraft-provided correlation pieces. 

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. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 

Refer to Doc 362 “Soldering Surface Mount Components” before soldering. 

- **Q** = 7″ machine-ready reel. EIA-481 punched paper tape (5000 parts per full reel). 

- **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.
