Operating Temperature -55°C to 275°C Storage Temperature 15℃-35℃, humidity: 25%-75% 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. Fea TureS
