INTRODUCTION

These Bulk Metal

Z-Foil power current sensing resistors are

direct replacements for certain wirewound devices but

without the inductive characteristics of wirewounds. The

anodized aluminum housing is drilled and countersunk to

accept flat head screws for thermal mounting. Because the

device is internally Kelvin connected, there is no restriction

on the lead lengths as would be the case if this were a two

terminal device. Frequently used in YIG oscillator circuits

these devices contribute to superior frequency stability.
