Pennsylvania-based Vishay Intertechnology, Inc. (Vishay) recently announced that its Vishay Milwaukee GRE1, GRE2 and NGR grid resistors are now available with a new stainless steel resistive element material optimized for applications requiring a more stable TCR (Temperature Coefficient of Resistance). Vishay is a manufacturer of discrete semiconductors and passive electronic components for the industrial, computing, automotive, consumer, telecommunications, military, aerospace, power supplies and medical markets.
Vishay grid resistors utilizing the new magnetic stainless steel material provide a TCR of ± 365 ppm/°C and deliver superior performance and corrosion resistance for dynamic braking resistors, testing load banks, motor control and other applications requiring a minimal change in resistance as the elements increase in temperature. Devices utilizing a non-magnetic stainless steel alloy offer a TCR of ± 930 ppm/°C and are optimized for harmonic filtering and current limiting applications, in addition to those requiring reduced noise emissions, such as dynamic braking in elevators and other industrial equipment.
