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 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 industrial power supplies, motor controls, and other high-power dissipation scenarios requiring robust and reliable performance.
