INTRODUCTION
Billions of products are already in use
worldwide in all types of applications-from
process control instrumentation to telephone
receivers and FM radio to color television.
The secret is in a proprietary production
system and baking by a uniquely designed and
automated production technique. Years of
experience in making raw materials and
production machinery prove the unique
quality and high reliability of these products.
The meet-or far exceed-such specifications as
EIA RS196A. JIS-C-6402 and IEC-115.
The resistors are coated with layers of tan
color lacquer.
