DerATiNg CurVe  
For resistors operated in ambient temperatures above 70°C, power rating must be derated  
in accordance with the curve below.

The MFR Series Metal Film Resistors are  
manufactured using a vacuum sputtering system  
to deposit multiple layers of mixed metal  
alloys and passivative materials onto a carefully  
treated high grade ceramic substrate. After a  
helical groove has been cut in the resistive layer,  
tinned connecting leads of electrolytic copper  
are welded to the end-caps. The resistors are  
coated with layers of blue color lacquer.
