Metal Oxide Film Resistor (RSS Series)

FEATURES :

   
Flameproof and insulating coating designed to assure safe    
usage by special non-flammable silicon-base    
Resistor elements have stable characteristics due to    
thermally and chemically stable materials used    
High thermal stability and low surface temperature rise    
Low cost with excellent performance    
Small size film resistors are suitable for high density circuit    
applications
