SMT Power Inductors
–
SPT Series
• Toroid winding eliminates stray electromagnetic emissions
• Two versions: Standard, current ratings up to 8 Amps;
High current, with ratings up to 13.9 Amp
Core material Powered iron
Core and winding loss See www.coilcraft.com/coreloss
Terminations RoHS compliant tin-silver over copper. Other
terminations available at additional cost.
Ambient temperature –40°C to +85°C
Maximum part temperature: The part temperature should not
exceed +85°C (ambient + self-heating). Prolonged operation
above +85°C may result in a permanent increase in core loss and
part failure due to thermal aging of the core material.
Storage temperature Component: –40°C to +85°C.
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)
38 per billion hours / 26,315,789 hours, calculated per Telcordia SR-332
PCB washing Only pure water or alcohol recommended
