7 mm tunable rf coils C 146, 150 document 109-1 document 109-1 revised 09/30/08 coilcraft tunable coils provide the compactness of a 7 mm coil and the low drift reliability of an insert molded coil. standard inductance values range from less than 50 nh to over 500 nh. 150 series coils with a tap are also avail - able to meet specifc requirements. the windings of these economical coils are precision molded into a single piece of polypropylene for mechani - cal and electrical stability. optional plated brass shield cans with solderable tabs provide integral shielding and additional mounting stability. these parts can be ordered without cores for use as fxed inductors. coilcraft designers kit m302 contains samples of all standard 7 mm and 10 mm tunable inductors. to order, contact coilcraft or visit http://order.coilcraft.com . unshielded styles with shield can terminations: series 146 leads: tin-silver over copper series 150 leads: matte tin over copper shield can tabs: tin-silver over nickel over brass 0.039 0.010 1,0 0,25 0.138 0.010 3,51 0,25 0.216 5,5 0.475 12,1 max dia hole ta b length 0.280 7,1 ta b centers 0.300 7,6 max finish star t 0.177 0.005 4,5 0,13 0.138 0.040 3,5 1,02 0.020 0.002 0,51 0.05 0.177 0.005 4,5 0,13 0.450 0.020 11,43 0,51 0.268 0.005 6,81 mm 0,13 square dia finish star t recommended boar dl ay out c l c l 0.0885 2,25 0.0885 2,25 0.140 3,55 (2) 0.040 1,016 0.060 1,52 (f or shield can tabs) unshielded with shield can weight: 146 series 0.44 C 0.70 g 0.91 C 1.12 g 150 series 0.45 C 0.61 g 0.88 C 1.08 g packaging: 80 per tube 75 per tube resistance to soldering heat: wave solder only. recommended maximum board surface temperature of 168c (334f) for no more than three seconds. pre-heating is recommended to minimize time over the solder nozzle. dimensions are in inches mm us uk t aiwan china singapore +1-847-639-6400 sales@coilcraft.com +44-1236-730595 sales@coilcraft-eur ope.com +886-2-2264 3646 sales@coilcraft.com.tw +86-21-6218 8074 sales@coilcraft.com.cn + 65-6484 8412 sales@coilcraft.com.sg ? coilcraft inc. 2013 this pr oduct may not be used in medical or high risk applications without prior coilcraft appr oval. specification subject to change without notice. please check web site for latest infor mation.
