1. When ordering, please specify **termination** and **packaging** codes: | ~~———_~~ 

**0403HQ-18NXJEW** 

**Termination: E** = Halogen free component. RoHS compliant silverpalladium-platinum-glass frit terminations. 

   - **L** = RoHS compliant, not halogen-free. Silver-palladiumplatinum-glass frit terminations. 

   - 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). 

   - **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. 

2. Inductance measured at 500 MHz using a Coilcraft SMD-F fixture in an Agilent/HP 4286 impedance analyzer with Coilcraft-provided correlation pieces. 

3. Q measured at 500 MHz using an Agilent/HP 4291A with an Agilent/ HP 16193 test fixture.

**Maximum part temperature** +155°C (ambient + temp rise). 

**Storage temperature** Component: –40°C to +155°C. Tape and reel packaging: –40°C to +80°C 

**Resistance to soldering heat** Max three 40 second reflows at +260°C, parts cooled to room temperature between cycles 

**Temperature Coefficient of Inductance (TCL)** +25 to +125 ppm/°C **Moisture Sensitivity Level (MSL)** 1 (unlimited floor life at <30°C / 85% relative humidity) 

**Packaging** 2000 per 7″ reel; 7500 per 13″ reel; Paper tape: 8 mm wide, 1.0 mm thick, 2 mm pocket spacing, **PCB washing** Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. See Doc787_PCB_Washing.pdf. 

5. DCR measured on a micro-ohmmeter and a Coilcraft CCF858 test fixture. 

6. Current that causes a 30°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
