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. Please
