Type 409 Series
The 409 series offers typical Tyco
features, the stability of a cermet
resistive element, and an attractive
price. The range satisfies many
applications in industrial and
professional equipment. Components
are available with top, underside, side,
finger, auto and skeleton adjustments.
The 409 is widely used in power
supplies, telecommunications, medical
instrumentation and the automotive
industry.
