4700 series dual winding surface mount inductors features 1.0? to 400? 1 up to 9.5a idc bobbin format dual winding surface mounting integral emi shield compact size t ape and reel packaging description the 4700 series is a range of dual wound inductors offering flexible options. windings can be connected in series or parallel to create a wide range of inductance combinations. they can also be used as common mode chokes or 1:1 transformers with the secondary winding used as a feedback winding in switched mode power supplies. 1w hen connecting windings in series, inductance will be 4 times the nominal figure shown. 2 specifications typical at ta=25? 3i f current is flowing in both windings the maximum dc current occurs when either the inductance falls to 85% of its nominal value or when its temperature rise reaches 40?, whichever is sooner. p ackage details order code typ weight (g) packaging style 47xxx 2.5 tape & reel mechanical dimensions selection guide 2 nominal inductance dc current dc inductance 1 range continuous 3 resistance ? ? a max m ? 10khz,100mv 10khz, 100mv 1&2 s/c to max order code 1&3, 2&4 1&3, 2&4 3&4 s/c 1&3, 2&4 471R0 1.0 0.83 - 1.39 9.50 8.9 472r2 2.2 1.38 - 2.30 6.80 13.7 473r3 3.3 2.87 - 4.79 5.50 23.3 474r7 4.7 4.08 - 6.12 4.60 32.4 476r8 6.8 5.24 - 7.86 3.90 44.8 47100 10 8.00 - 12.0 3.20 70.2 47150 15 11.3 - 17.0 2.60 106 47220 22 17.4 - 26.1 2.10 165 47330 33 27.6 - 41.4 1.80 207 47470 47 36.7 - 55.1 1.47 298 47680 68 54.9 - 82.3 1.22 456 47101 100 81.4 - 122 1.01 686 0.480?.30 (12.20?.012) 0.480 ?.30 (12.20 ?.012) 2 1 3 4 0.197(5.00) max 0.591(15.0) 0.197(5.00) all dimensions in inches (mm) absolute maximum ratings operating free air temperature range ?0? to 85? storage temperature range ?0? to 125? pin connections (top view) 1 2 3 & 1 = primary winding 4 & 2 = secondary winding 4 3 order reel reel outline dimensions code quantity n w1 w2 w3 47xxx 750 2.362 0.961 1.197 0.914-1.079 ( 60.0) (24.4) (30.4) (23.9-27 .4) all dimensions in inches(mm). controlling dimension in mm. reel dimensions (see fig.1) www.cdpoweronline.com 0.039(1.00) 0.197 (5.00) recommended footprint details t ape and reel specifications shall conform with standards iec 60286-3 & eia-481-c peel force and speed of cover tape; 0.1-1.3n @300?0mm/min, the angle between the cover tape during peel-off and the direction of unreeling shall be 165-180? the break force of the cover tape shall be 10n min. the carrier tape leader section shall include a minimum 100mm length of empty carrier tape sealed by the cover tape (see fig.1). the maximum number of missing components shall be one or 0.1%, whichever is greater. in no case shall there be two or more consecutive components missing. the trailer section shall consist entirely of empty carrier tape sealed by the cover tape. the carrier tape shall be released from the reel hub as the last portion of the carrier tape unwinds from the reel. sprocket hole pitch tolerance over any 10 pitches ?.2mm. carrier tape camber shall not exceed 1mm/250mm in either direction. t ape & reel specifications order tape outline dimensions code a0 b0 e2 f k0 p1 w 47xxx 0.496 0.496 0.876 0.453 0.205 0.630 0.945 (12.6) (12.6) (22.3) (11.5) (5.2) (16.0) (24.0) all dimensions in inches(mm). controlling dimension in mm. t ape dimensions (see fig.2)
