The UAR range of high precision resistors represents a significant technical advancement in resistive technology, combining low temperature coefficients with high environmental stabilities, and high frequency performance. Laser beam trimming gives tolerance accuracies from 0.02 % to 1 %. The UAR range effectively bridges the gap that has hitherto existed between the high precision, high stability networks or wirewound technology and conventional film technology. Full lines equate Vishay, IRC, Ohmite, Caddock, Panasonic precision resistors with fast delivery and more competitive price.
