Key Features

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

trimmers yet now suitable for s.m.

applications.
