TWM3JR05E

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. TWM/TWW Series Ceramic Housed Radial Terminal Power 0.49" ±.04 12.5mm ±1 0.35" ±.04 9 mm ±1 FEATURES • Economical Commercial Grade for general purpose use • Wirewound and Metal Oxide construction • Wide resistance range • Flameproof inorganic construction SPECIFICATIONS Material Housing: Ceramic Core: Fiberglass or metal oxide Filling: Cement based Electrical Tolerance: 5% standard Temperature coeff.: .01-20Ω ±400ppm/°C 20-10Ω ±350ppm/°C Dielectric withstanding voltage: 1,000VAC Short time overload: TWW: 10x rated power for 5 sec.
