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. • Economical Commercial Grade for general purpose use • Wirewound and Metal Oxide construction • Wide resistance range • Flameproof inorganic construction SERIES SPECIFICATIONS Derating Curve Housing Ceramic Core Fiberglass or metal oxide Filling Cement based Tolerance 5% standard TCR 0.01-20Q ±400ppm/°C 20-150KQ ±350ppm/°C Dielectric withstanding 1,000VAC voltage Short time overload TUW: 10x rated power for 5 sec. TUM: 5x rated power for 5 sec. www.ohmite.com • [email protected]
