**Failures in Time (FIT) / Mean Time Between Failures (MTBF)** 38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332 **Packaging** 750/13″ reel Plastic tape: 24 mm wide, 0.35 mm thick, 12 mm pocket spacing, 6.4 mm pocket depth 

**PCB washing** Only pure water or alcohol recommended 

## 1. When ordering, specify **tolerance** , **termination** and **packaging** codes: —_, ~~|__|~~ **DO3316T-474MLD** 

**Tolerance:  M =** 20%, **K** = 10% (Table shows stock tolerances in bold.) **Termination: L** = RoHS compliant tin-silver 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 (750 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 tested at 100 kHz, 0.1 Vrms, 0 Adc. 

3. Tolerances in bold are stocked for immediate shipment. 

4. SRF measured using Agilent/HP 8753D network analyzer. 

5. DC current at which the inductance drops 10% (typ) from its value without current. 

6. Current that causes a 40°C temperature rise from 25°C ambient. 

7. Electrical specifications at 25°C.
