**PCB washing** Only pure water or alcohol recommended
1. When ordering, please specify **termination** and **packaging** codes: | ~~———_~~
**DO5040H-104MLD**
**Termination: L** = RoHS compliant tin-silver (96.5/3.5) over copper. **Special order:**
- **T** = RoHS tin-silver-copper (95.5/4/0.5) or **S** = non-RoHS tin-lead (63/37).
- **Packaging: D** = 13″ machine-ready reel. EIA-481 embossed plastic tape (175 parts per full reel).
- **B** = Less than full reel. In tape, but not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using Coilcraft SMD-A fixture in Agilent/HP 4284A impedance analyzer.
3. SRF measured using Agilent/HP 8753D network analyzer and Coilcraft SMD -D test fixture.
4. DC current at which the inductance drops 10% (typ) from its value without current.
5. Current that causes a 40°C temperature rise from 25°C ambient.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
