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 and the leads are connected to
the caps by welding. The resistors are coated
with layers of green color flame-proof lacquer.
For resistors operated in ambient temperatures above 40°C, power rating must be derated
in accordance with the curve below.
