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)
