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.
