Product Description
Product Overview
The Vishay Sfernice RSSD series offers industrial high-power, vitreous tubular, adjustable wirewound resistors. Designed for demanding applications, these resistors provide high power ratings from 16 W to 600 W at 25 C, excellent thermal shock resistance, and mechanical strength. They are suitable for heavy transient conditions and severe shock and vibration environments, complementing lower ohmic value ranges.
