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.
• Non hot spot design
• Terminal finishes available: lead (Pb)-free
Model 300145 is a pair-of 300144 elements back to back in
a single molded package.
tin/lead alloy
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.
• Any value available within resistance range (e.g. 1K2345)
• Prototype samples available from 48 h. For more
information, please contact foil@vishay.com
• For better performances see 300144Z, 300145Z (Z-Foil)
