New Products: Resistor networks with enhanced precision and stability
A family of precision resistor networks using Tantalum Ultride film material on high-purity alumina substrates is said to provide better corrosion resistance than traditional nichrome films, as well as enhanced precision and stability.
The networks
are not susceptible to dendritic growth as they do
not use internal solder connections.
The DIP-U and SIP-U Series devices feature resistance
ranges from 1-to-100 kΩ with a resistor-element
power rating of 0.040 W at 70°C. The SON-U and PFC-UD
networks offer a resistance range of 1-to-50 kΩ, with
a resistor-element power rating of 0.025 W at 70°C. All
four networks feature absolute TCR to ±10 ppm/°C and
tracking TCR to ±1 ppm/°C, with a voltage coefficient of
<0.1 ppm/V. Absolute tolerance is to ±0.02% with a ratio
tolerance of ±0.01%. Operating temperature range is
from –55 to 125°C.
