Vishay / Dale RS & NS Industrial Wirewound Resistors

Vishay / Dale RS and NS Industrial Wirewound Resistors provide high reliability, an all-welded construction, and high-temperature capability. These silicone-coated, axial lead resistors offer precision power, excellent stability in operation with <0.5% typical resistance shift, high-temperature coating (>350°C), and down to ±20ppm/°C temperature coefficient of resistance (TCR). Both series meet the applicable requirements of MIL-PRF-26. Other features include a 0.4W to 13W power rating, 0.1Ω to 273KΩ resistance value range, and ±0.05% to ±10% tolerance range. The resistors are available in non-inductive styles (type NS) with Ayrton-Perry winding for the lowest reactive components. Applications for Vishay / Dale RS and NS Industrial Wirewound Resistors include DC/DC converters, AC/DC inverters, high-voltage bleeders, motor speed controls, electrical loads, current shunts, and more.
