Ultra Precision Networks | IRC

These ultra precision resistor networks are constructed with a corrosion resistant material that provides enhanced precision and stability. The tantalum ultride material provides superior corrosion resistance to traditional nichrome films, as well as enhanced precision and stability.  The DIP and SIP networks feature a resistance range of 1KΩ to 100KΩ with a resistor element power rating of 0.040 watts @ 70°C. The SON and PFC-UD networks are offered in a resistance range of 1KΩ to 50KΩ, with a resistor element power rating of 0.025 watts @ 70°C. All four high stability networks feature absolute TCR to ±10ppm/°C and tracking TCR to ±1ppm/°C, with a voltage coefficient of <0.1ppm/volt. Absolute tolerance is to ±0.02% and ratio tolerance is to ±0.01%. Operating temperature range is from -55°C to +125°C.
