INTRODUCTION
Vishay Foil precision trimmers have the Bulk Metal® Foil
resistive element which possesses a unique inherent
temperature and load life stability. Plus, their advanced
virtually back lash-free adjustment mechanism makes them
easy to set quickly and accurately and keeps the setting
exactly on target.
