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 loads, severe shock, and vibration conditions. They are particularly suited for low ohmic value requirements and can be tapped using adjustable collars for flexible configuration. Key advantages include high power ratings, excellent thermal shock resistance, mechanical strength, and fire-proof construction.
