shielded power inductors C slc1480 document 482-1 document 482-1 revised 03/02/11 the slc1480 is designed for high-speed switch mode applications requiring low inductance and very high saturation current ratings. while requiring a mere quar - ter square inch of board space, it can handle current as high as 130 a. these shielded inductors are ideal for use in multi-phase vrm/vrd regulators and high current/high frequency dc/dc converters. for free evaluation samples, contact coilcraft or order them on-line at www.coilcraft.com. 1. when ordering, please specify packaging code: slc1480-321ml d packaging: d = 13 machine-ready reel. eia-481 embossed plastic tape (500 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 using an agilent/hp 4284. 3. dcr is measured between the two points indicated below. p oints used f or measur ing dcr 4. srf measured using an agilent/hp 8753es network analyzer or equivalent. 5. dc current at which the inductance drops from its value without current. 6. current that causes the specifed temperature rise from 25c ambient. 7. electrical specifcations at 25c. refer to doc 362 soldering surface mount components before soldering. inductance 2 dcr (mohms) 3 srf typ 4 i sat (a) 5 i rms (a) 6 part number 1 20% (nh) min max (mhz) 10% drop 20% drop 30% drop 20c rise 40c rise slc1480-111ml_ 110 0.15 0.21 130 110 128 130 39 55 slc1480-131ml_ 130 0.15 0.21 110 97 110 112 39 55 slc1480-151ml_ 150 0.15 0.21 108 88 95 97 39 55 slc1480-171ml_ 170 0.15 0.21 75 80 87 90 39 55 slc1480-201ml_ 200 0.15 0.21 68 65 72 76 39 55 slc1480-231ml_ 230 0.15 0.21 59 57 64 67 39 55 slc1480-261ml_ 260 0.15 0.21 50 50 57 61 39 55 slc1480-301ml_ 300 0.15 0.21 46 42 49 52 39 55 slc1480-321ml_ 320 0.15 0.21 42 38 44 48 39 55 slc1480-441ml_ 440 0.15 0.21 35 28 32 35 39 55 core material ferrite terminations rohs compliant matte tin over nickel over copper. other terminations available at additional cost. weight 5.25 g ambient temperature C40c to +85c with i rms current, +85c to +125c with derated current storage temperature component: C40c to +125c. tape and reel packaging: C40c to +80c resistance to soldering heat max three 40 second refows at +260c, parts cooled to room temperature between cycles moisture sensitivity level (msl) 1 (unlimited foor life at <30c / 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 500/13 reel; plastic tape: 24 mm wide, 0.4 mm thick, 16 mm pocket spacing, 8.1 mm pocket depth pcb washing only pure water or alcohol recommended
