Document 481-1 SMT Power Inductors – SLC7649 Series • Designed for use in multi-phase VRM/VRD regulators and high current/high frequency DC/DC converters. • Requires only 60 mm2 of board space; can handle up to 100 A Core material Ferrite Core and winding loss See www.coilcraft.com/coreloss Terminations RoHS compliant matte tin over nickel over copper. Other terminations available at additional cost. Weight 0.9 g Ambient temperature –40°C to +85°C with Irms current, +85°C to +125°C with derated current Storage temperature Component: –40°C to +125°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 Packaging 250/7″reel; 1000/13″ reel Plastic tape: 16 mm wide, 0.35 mm thick, 12 mm pocket spacing, 5 mm pocket depth PCB washing Only pure water or alcohol recommended Part number1 SLC7649S-360KL_ SLC7649S-500KL_ SLC7649S-700KL_ SLC7649S-101KL_ SLC7649S-121KL_ SLC7649S-151KL_ L DCR SRF ±10%2 ±5%3 typ4 (nH) (mOhms) (MHz) 36 50 70 100 120 150 0.17 0.17 0.17 0.17 0.17 0.17 1150 900 750 110 78 67 Isat5 (A) Irms6 (A) 100 84 65 42 33 27 39 39 39 39 39 39 1. When ordering, please specify termination and packaging code: SLC7649S-101KLC Termination: L = RoHS compliant matte tin over nickel over copper Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or S = non-RoHS tin-lead (63/37). Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic tape (250 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. D = 13″ machine-ready reel. EIA-481 embossed plastic tape (1000 per full reel). Factory order only, not stocked. 2. Inductance tested at 100 kHz, 0.1 Vrms using an Agilent/HP 4263B LCR meter or equivalent. 3. DCR is measured between the two points indicated on the dimensional drawing. 4. SRF measured using an Agilent/HP 8753ES network analyzer or equivalent. 5. DC current at which the inductance drops 20% (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. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. 0.295 max 7,49 XXX Dash number X Internal code 0.300 max 7,62 0.195 max 4,96 Points used for measuring DCR 0.105 2,67 0.085 2,16 0.225 5,72 0.100 2,54 0.135 3,43 inches Dimensions are in mm Specifications subject to change without notice.
