deRatiNG CURVe
The resistor element is a resistive wire which
is wound in a single layer on a ceramic rod,
tinned connecting wires of electrolytic copper
are welded to the end-caps. The ends of the
resistance 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.
