Bulk Metal

INTRODUCTION

Vishay Foil precision trimmers have the Bulk Metal

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.
