deRatiNG CURVe

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.
