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 and severe shock and vibration conditions, making them suitable for low ohmic values and applications requiring adjustable resistance. They complement Vishay's RW, RWST, and RA styles in the low-value range and can be tapped using adjustable collars for precise resistance setting.
