TUM/TUW Series Ceramic Housed Axial Terminal Power The TUM/TUW Series resistors are our most eco- nomical power resistors. They are recommended for commercial applications where low cost is critical. They are available in small standard packs for standard values, or bulk packaged for even lower FeaTUreS costs. • Economical Commercial Grade for general purpose use • Wirewound and Metal Oxide construction • Wide resistance range • Flameproof inorganic construction SerIeS SPeCIFICa TIONS Series Wattage Ohms Voltage Element TUW3 3 0.01-39 350 Wirewound TUW5 5 0.01-47 350 Wirewound TUW7 7 0.10-680 500 Wirewound TUW10 10 0.10-990 750 Wirewound TUW15 15 0.10-1000 1000 Wirewound TUM3 3 180-33K 350 Metal oxide TUM5 5 220-50K 350 Metal oxide TUM7 7 910-50K 500 Metal oxide TUM10 10 1000-50K 750 Metal oxide TUM15 15 1100-150K 1000 Metal oxide CharaCTerISTICS Housing Ceramic Derating Curve Core Fiberglass or metal oxide 100 Filling Cement based Tolerance 5% standard Watts80 d 60 TCR 0.01-20Ω ±400ppm/°C ate 20-150KΩ ±350ppm/°C nt R40 e Dielectric withstanding 1,000VAC erc20 P voltage 0 Short time overload TUW: 10x rated power for 5 sec. 70 100 150 200 250 275 Ambient Temperature, (cid:111)C TUM: 5x rated power for 5 sec.
