RES-TWW-TWM Datasheet, PDF (1/2 Pages) Ohmite Mfg. Co. – Wide resistance range

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
