TWM3J270E

Ceramic Housed Radial Terminal Power

Ohmite Mfg. Co. 

The TWM/TWW series radial terminal power resistors offer

significant board space savings over axial terminal products.

Generated heat is also kept away from the circuit board.

They are recommended for commercial applications requiring

low cost.

FEATURES

• Economical Commercial Grade

for general purpose use

• Wirewound and Metal Oxide

construction

• Wide resistance range
