## **– Shielded Power Inductor SER2000** 

- Designed for high current  power supply applications 

- Flat wire windings provide exceptionally low DCR • I sat ratings as high as 100 A 

**Designer’s Kit C374** contains 2 each of nine parts. **Core material** Ferrite 

**Core and winding loss** See www.coilcraft.com/coreloss **Terminations** RoHS compliant tin-silver-copper over copper. Other terminations available at additional cost. 

**Ambient temperature** –40°C to +85°C with (40°C rise) I rms current. **Maximum part temperature** +125°C (ambient + temp rise). Derating. **Storage temperature** Component: –40°C to +125°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 

**Moisture Sensitivity Level (MSL)** 1 (unlimited floor life at <30°C / 85% relative humidity) 

**Failures in Time (FIT) / Mean Time Between Failures (MTBF)** 0.48 per billion hours / 2.083E+09 hours, calculated per Telcordia SR-332 **PCB washing** Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. See Doc787_PCB_Washing.pdf.
