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 suitable for low ohmic value applications and can be tapped using adjustable collars for flexible resistance adjustment. Key advantages include high power ratings, excellent thermal shock resistance, mechanical strength, and fire-proof construction.
