Power Metal Film Resistors  
FEATURES  
High power in small packages  
Different lead materials for different applications  
Defined interruption behaviour.  
APPLICATIONS  
All general purpose power applications  
A homogeneous film of metal alloy is deposited on a high  
grade ceramic body. After a helical groove has been cut in  
the resistive layer, tinned connecting wires of electrolytic  
copper or copper-clad iron are welded to the end-caps. The  
resistors are coated with a red, nonflammable lacquer which  
provides electrical, mechanical and climatic protection. This  
coating is not resistant to aggressive fluxes. The  
encapsulation is resistant to all cleaning solvents in  
accordance with “MIL-STD-202E, method 215”, and  
“IEC 60068-2-45”.
