Product Description
Product Overview
The Vishay Sfernice RSSD series offers industrial high-power, vitreous tubular, adjustable wirewound resistors designed for demanding applications. These resistors are known for their ability to withstand heavy transient conditions, severe shock, and vibration. They are particularly suited for low ohmic value requirements and can be tapped using adjustable collars for flexible resistance adjustments. The series provides high power ratings from 16 W to 600 W, excellent thermal shock resistance, and long-term stability.
