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 ideal for complementing lower ohmic ranges and can be tapped using adjustable collars for flexible resistance adjustment. Applications include general industrial use where high power handling and robustness are required.
