TWM/TWW Series

Ceramic Housed Radial Terminal Power

The TWM/TWW series radial terminal power resis-

tors offer significant board space savings over axial

terminal products. Generated heat is also kept away

from the circuit board.

They are recommended for commercial applica-

tions requiring low cost.

F e aT u r e S

• Economical Commercial Grade for general purpose

use

• Wirewound and Metal Oxide construction

• Wide resistance range

• Flameproof inorganic construction
