333 3 RSSD www.vishay.com Vishay Sfernice Wirewound Resistor, Industrial High Power, Vitreous Tubular, Adjustable, Low Values 0.12 to 560 FEATURES High power rating: 16 W to 600 W at 25 C Heavy overloads 10 P 5 s 1 % n Low ohmic values 0.10 available High long term stability drift < 1.5 % after 1000 h Excellent withstanding of thermal shock Mechanical strength Fire proof Material categorization: for definitions of compliance please see www.vishay.com/doc 99912 LINKS TO ADDITIONAL RESOURCES 3D Models RSSD medium and high power resistors are noted for their ability to withstand heavy transient and severe shock and vibration conditions. They complement the ohmic range of Vishay styles RW, RWST and RA in the low value area, and can be tapped by means of adjustable collars. Standard RSSD resistors have a single adjustable collar.
