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