Product Description

The Vishay Sfernice RSSD series are industrial high-power, vitreous tubular, adjustable wirewound resistors designed for demanding applications. They offer high power ratings from 16 W to 600 W at 25 C, with excellent capability to withstand heavy overloads (10 Pn for 5 s with < 1 % drift). These resistors are suitable for applications requiring low ohmic values (down to 0.10 ) and exhibit high long-term stability with drift < 1.5 % after 1000 hours. They are known for their excellent thermal shock resistance, mechanical strength, and fire-proof properties. The RSSD series complements existing Vishay styles in the low-value area and can be tapped using adjustable collars for flexible resistance adjustments. Standard models feature a single adjustable collar.
