? Coilcraft, Inc. 2007 Specifications subject to change without notice. Please check our website for latest information. T unable RF Inductors – 148 Series Document 111 Document 111 Revised 04/27/05 With an overall height of only 0.300″, these tunable coils are ideal for applications where low-profile circuit boards are essential. The windings are precision molded in plastic to guaran- tee a constant winding pitch and a consistent relation- ship to the printed circuit board. Tuning is done by means of a threaded Carbonyl J core. Coilcraft Designer’s Kit M304 contains three samples each of the values shown plus 20 values from the 132 Series of low-profile, high Q fixed inductors.
