The USGS series from Caddock are high voltage, ultra stable, low TCR selected resistor sets. The resistance values available for the complete sets are 300MΩ and 500MΩ all with a TCR of 5 ppm/°C and a tolerance of ±0.10% for each set. The USGS resistor sets are designed for use in high voltage systems that require excellent temperature and long term stability. These are manufactured with Caddock’s Tetrinox® resistance film system, the individual resistors that form these sets are individually characterized using automated data acquisition systems and then selected to form a set resistance.
Multiple USGS selected resistor sets can be used in series to form a string of resistors that achieve a higher total resistance and a higher voltage rating with 5 ppm/°C overall temperature coefficient.
The below table gives the specifications available for the complete USGS series:
