TUM/TUW Series Ceramic Housed Axial Terminal Power The TUM/TUW Series resistors are our most economical 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 costs. F e a tu r e s •Economical Commercial Grade for general purpose use •Wirewound and Metal Oxide construction •Wide resistance range •Flameproof inorganic construction S ER I E S S P E C I F I C A T I O N S Series TUW3 TUW5 TUW7 TUW10 TUW15 TUM3 TUM5 TUM7 TUM10 TUM15 Wattage 3 5 7 10 15 3 5 7 10 15 Ohms 0.01-39 0.01-47 0.10-680 0.10-990 0.10-1000 180-33K 220-50 910-50K 1000-50K 1100-150K Voltage 350 350 500 750 1000 350 350 500 750 1000 Element Wirewound Wirewound Wirewound Wirewound Wirewound Metal oxide Metal oxide Metal oxide Metal oxide Metal oxide c h a r a ct e r istics Core Fiberglass or metal oxide Filling Cement based Tolerance 5% standard TCR 0.01-20Ω ±400ppm/°C 20-150KΩ ±350ppm/°C Dielectric withstanding 1,000VAC voltage Short time overload TUW: 10x rated power for 5 sec.
