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.
