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 useful in the low ohmic value range and can be tapped using adjustable collars for flexible resistance configuration. The RSSD series complements existing Vishay styles RW, RWST, and RA.
