A very popular range is this 13mm
diameter spindle operated potentiome-
ter family. The LC1 Series has a cermet
resistance element. This technology
provides excellent electrical and
thermal stability, reliability, low noise
and
long
life,
to
meet
most
professional or military applications for
small size potentiometers. Recent
changes have meant that the LC type
is no longer released to BS CECC
specification.
