Type 3270 Series
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.
