3/8" Square Multi-Turn Cermet Trimmer
The T93 is a small size trimmer - 3/8" x 3/8" x 3/16" -
answering PC board mounting requirements.
Five versions are available which differ by the position of the
control screw in relation to the PC board plane and by the
spacing of the terminals.
Excellent operational stability is provided by the use of a
cermet element.
