IRC “B” Series Resistors
These resistors offer power ratings up to 4 times higher than standard power wirewound resistors of equal size, thanks to a finer heat dissipation pattern.
Key Features:
Heat Dissipation: Beryllia core provides the finest possible pattern.
Power Rating: Up to 4 times higher than conventional resistors, depending on physical size.
Wattage: From 0.25 to 18 watts.
Temperature Coefficients: Standard and special options available, ranging from -20 PPM/C to +6000 PPM/C.
Tolerance: From ±1% to ±0.1%.
Resistance Values: From 150K ohms to 150K ohms.
Coating: Special high-temperature silicone coating, impervious to moisture, salt water immersion, and abrasion.
