Product Overview
The Vishay Sfernice RSSD series offers industrial high-power vitreous tubular resistors with adjustable capabilities. Designed for demanding applications, these resistors provide high power ratings from 16 W to 600 W at 25 C, excellent withstanding of thermal shock, and robust mechanical strength. They are particularly noted for their ability to handle heavy transient loads and severe shock and vibration conditions, complementing lower ohmic values in the Vishay RW, RWST, and RA styles. Adjustable collars allow for precise tapping.
