The UAR range of high precision resistors represents a signicant technical advancement in resistive technology,
combining low temperature coefcients 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 lm technology.
Full lines equate Vishay, IRC, Ohmite, Caddock, Panasonic precision resistors with fast delivery and more
competitive price.
The metal lm series is RoHS compliant with Pb-free terminations. Detailed specications, both mechanical and
electrical, please contact our sales representative for more information.
Mil-Std-202 Standard :
This standard establishes uniform methods for testing electronic and electrical component parts,
including basic environmental tests to determine resistance to deleterious effects of natural elements
and conditions surrounding military operations, and physical and electrical tests.
