IRC High Stability Resistor Networks

The 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 ultra precision networks are ideal for medical applications, including CT machines, MRI, PET and ultrasound equipment; petrochemical exploration and data logging instruments; instrumentation and test instruments including DMMs, measurement bridges, strain gauge circuits and input attenuators; as well as missile guidance and military avionics. 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.
