Vishay RS and NS Series Wirewound Resistors
Vishay Dale RS and NS Series Wirewound Resistors are available in non-inductive styles (type NS) with Ayrton-perry winding for the lowest reactive components. The RS and NS wirewound resistors are excellent in stability operation with a typical resistance of shift less than 0.5%. These RS and NS resistors offer high temperature coating of greater than 350°C and a temperature coefficient of ±20ppm/°C, ±50ppm/°C, and ±90ppm/°C. RS and NS wirewound resistors operate at temperatures ranging from -65°C to +250°C and -65°C to +350°C. Typical applications include aerospace, automotive, defense, industrial automation, instrumentation, medical devices, power supplies, renewable energy systems, and telecommunications.
