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.
