Product Description
Product Description
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 and severe shock and vibration conditions. They are suitable for low ohmic value requirements and can be tapped using adjustable collars. Key advantages include high power ratings, excellent thermal shock resistance, mechanical strength, and fire-proof construction. They complement lower value ranges of Vishay styles RW, RWST, and RA.
