■2W Power Rating
■Strong Construction
■Sealed to Military Standard
■Panel Sealed (MC1)
■Rugged Terminations
Type M Series
This is one of Tyco's most popular
ranges and is available with cermet
resistance elements. This choice
means that components offer excellent
electrical and thermal stability,
reliability, low noise and long life which
makes them most suitable for the
majority of professional applications.
The MC Series is used in the Tornado
Project and is the standard single turn
general purpose panel control used for
most military applications in the UK
and in Europe.
