Document 109-1 7 mm Tunable RF Coils – 146, 150 Series 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 0.05 µH to over 0.5 µH. 150 Series coils with a tap are also available to meet specific requirements. The windings of these economical coils are precision molded into a single piece of polypropylene for mechanical and electrical stability. Optional plated brass shield cans with solderable tabs provide integral shielding and additional mounting stability. These parts can be odered without cores for use as fixed inductors. Coilcraft Designer’s Kit M302 contains samples of all standard 7 mm and 10 mm tunable inductors. To order, contact Coilcraft or visit http://order.coilcraft.com.
