Document 280-1 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 Ferrite 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 L at 0A2 ±20% (µH) Part number1 Standard series SPT20L-112ML_ 1.1 SPT38L-382ML_ 3.8 SPT30L-522ML_ 5.2 SPT20L-702ML_ 7.0 SPT38L-752ML_ 7.5 SPT44L-792ML_ 7.9 SPT30L-123ML_ 12 SPT44L-143ML_ 14 SPT50L-163ML_ 16 SPT38L-223ML_ 22 SPT20L-233ML_ 23 SPT50L-263ML_ 26 SPT30L-353ML_ 35 SPT44L-413ML_ 41 SPT38L-733ML_ 73 SPT50L-733ML_ 73 SPT30L-174ML_ 170 SPT38L-294ML_ 290 SPT50L-564ML_ 560 SPT38L-674ML_ 670 SPT44L-115ML_ 1100 SPT50L-205ML_ 2000 High current series SPT44H-282ML_ 2.8 SPT44H-422ML_ 4.2 SPT50H-652ML_ 6.5 SPT50H-842ML_ 8.4 SPT68H-113ML_ 11 SPT68H-183ML_ 18 L typ3 (µH) DCR max (mOhm) 1.01 2.5 3.8 6.2 5.1 4.9 9.4 9.0 9.3 16.2 17.6 16.1 29.7 29.1 58.1 50 114 192 350 383 670 1070 16.0 9.3 19.9 95.0 18.7 16.2 47.2 23.6 19.7 63 320 32 166 85 290 133 640 657 550 1200 1908 1932 1.68 2.5 3.5 4.7 6.5 10.0 4.6 6.6 7.2 8.5 8.2 12.5 SRF typ4 (MHz) 360 133 60 70 73 49 33 20 19 34 21 9.2 12.0 9.5 5.0 14.0 3.3 2.3 1.0 1.2 0.73 0.40 136 72 46 23 20 9 1.
