Revised 9/30/08
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 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 mechani-
cal 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,
