Product information "USGS Ultra-Stable Low TC Resistor Sets"
Selected High Voltage Resistor Set; 300, 500 MΩ; ±0.1%; Silicone Conformal Encapsulation; Film
Caddock Electronics’ USGS series of ultra-stable selected resistor sets are designed for use in high-voltage systems that require excellent temperature stability and long-term stability. The resistors used in these selected resistor sets are manufactured with Caddock Electronics’ Tetrinox® resistance film system.
The individual USG style resistors that form the USGS series ultra-stable selected resistor sets are individually characterized using automated data acquisition systems and then selected to form a set resistance with an absolute temperature coefficient (TC) of 5 ppm/°C maximum. The low voltage coefficient (VC) of the USG1110 style resistors used in these selected resistor sets achieves excellent voltage stability over the operating voltage range.
Multiple USGS selected resistor sets can be used in series to form a string of resistors that achieves a higher total resistance and a higher voltage rating with 5 ppm/°C overall temperature coefficient. For custom selected resistor sets that precisely match your design project’s requirements please contact AMS Technologies applications engineering.
