Vishay RS SeriesVishay RS series of wirewound resistors are a precision power axial lead resistor with a high temperature silicone coating. The RS series has a complete welded construction with copper-nickel alloy or nickel-chrome alloy element, depending on resistance value.High temperatureComplete welded constructionExcellent operational stabilitySilicone Coated AxialWire-wound power resistors manufactured to a very high standard and employing a ruggedised welded cap and lead method of construction giving considerable strength and resistance to damage. The element is wound onto a ceramic former and coated with a non-inflammable silicone cement.
