300144, 300145 Vishay Foil Resistors High Precision Voltage Divider Resistors with TCR Tracking to 0.5 ppm/°C and Tolerance Match to 0.005 % (50 ppm) FEATURES Any value at any ratio available within resistance range INTRODUCTION Vishay Bulk Metal® foil technology outperforms all other technologies available today for applications that require high precision and high stability. Models 300144 and 300145 offer low TCR (both absolute and tracking), excellent load life stability, tight tolerance, excellent ratio stability, low thermal EMF, low current noise and non sensitivity to ESD - all in one package. Model 300145 is a pair-of 300144 elements back to back in a single molded package. By taking advantage of the overall stability and reliability of Vishay Bulk Metal foil resistors, designers can significantly reduce circuit errors and greatly improve overall circuit performances. Our application engineering department is available to advise and make recommendations. For non-standard technical requirements and special applications.
