TWM3J680

TWM/TWW Series Ceramic Housed Radial Terminal Power 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.
