WIREWOUND
RADIAL
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.
