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 useful for low ohmic value applications and can be tapped using adjustable collars for flexible resistance adjustment. Standard models feature a single adjustable collar.
