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 Fea TUreS costs.
