DESCRIPTION  
Dielectric withstanding voltage of  
the insulation for 1 minute  
700 V  
A metal glazed film is deposited on a  
high grade ceramic body. After a  
helical groove has been cut in the  
resistive layer, tinned electrolytic  
copper wires are welded to the  
end-caps. The resistors are coated  
with a light blue lacquer which  
provides electrical, mechanical, and  
climatic protection.  
The encapsulation is resistant to all  
cleaning solvents in accordance with  
“MIL-STD 202E, method 215” and  
“IEC 60068-2-45”.  
Basic specifications  
Climatic category (IEC 60068)

load (1000 hours)  
R/R max.: ±1.5% + 0.1 Ω  
accelerated damp heat test (6 days) R/R max.: ±1.5% + 0.1 Ω  
long term damp heat test (56 days)  
Noise  
R/R max.: ±1.5% + 0.1 Ω  
max. 5 µV/V
