TUM/TUW Series
Ceramic Housed Axial Terminal Power
The TUM/TUW Series resistors are our most eco-
nomical power resistors. They are recommended for
commercial applications where low cost is critical.
They are available in small standard packs for
standard values, or bulk packaged for even lower
costs.
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
