INTRODUCTION
The resistor element is a resistive wire which
is wound in a single layer on a ceramic rod,
with tinned connecting wires of electrolytic
copper welded to the end-caps. The ends of
the resistive wire are connected to the caps by
welding. The resistors are coated with layers of
green color flame-proof lacquer. High power in
small packages.
