TWM/TWW Series Datasheet

Ceramic Housed Radial Terminal Power 

Res Tww Twm product image

 

The TWM/TWW series radial terminal power resistors offer significantboard 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
  • Flameproof inorganic construction
