FEATURES
• 2W and 4W at 25°C
• NF C 83-210
• Good overload performance
• High reliability level
• Small size
• High electrical insulation
• Resistance to cleaning solvents
• Excellent climatic performances
• Good mechanical strength
The “ROP” resistors combine low price with outstanding
performance and are therefore suitable for both professional
and general purpose applications. These power metal oxide
fi lm resistors can favorably be used as a substitute for general
purpose cemented or lacquered wirewound resistors, in
medium and high ohmic values ranges.
