Product Description
Vishay Sfernice RSSD Series Wirewound Resistors
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 suited for low ohmic value requirements and can be tapped using adjustable collars for flexible configuration. Applications include general industrial, power supplies, and motor controls where high power dissipation and robust construction are essential.
