Tunables and Transformers
TT Series Data Sheet

 

Piconics TT Series, a molded top tuned inductor, is designed for use in high-density printed circuit boards where surrounding components prevent side tuning. It occupies one third the volume of a TO-5 can. The inductor has a molded case and utilizes a self-locking tuning screw. These inductors can be converted to transformers by additional taps and leads as required. Our standard construction uses solid .018" tinned copper leads for values below 1uH. From 1uH to 100uH .018 gold plated Kovar leads are used. For values above 100uH, .013" gold plated Kovar leads are used because the ratio of the winding wire to the lead wire is less and the weld reliability is higher. The series is listed in the Qualified Products List (QPL) 15305 under the identifier MS 53233 and 53234.
