This is the surface mount version of the
popular Tyco 4270. Top adjust and
low profile side adjust versions are
available in special high temperature
resistant packages. This multi-turn
device offers good setability, infinite
resolution and the other specification
features
typical
of
conventional
trimmers yet now suitable for s.m.
applications.
