The Vishay Sfernice RSSD series offers industrial high-power wirewound resistors with vitreous tubular construction, designed for demanding applications. These resistors are characterized by their high power rating, ability to withstand heavy overloads, low ohmic values, and excellent long-term stability. They are suitable for applications requiring robustness against transient conditions, shock, and vibration, and can be tapped using adjustable collars for flexible resistance adjustments. The resistors are fire-proof and possess excellent thermal shock resistance and mechanical strength.
