High precision resistor
50 Ω - 25 MΩ | USF Series Caddock Electronics

The USF Ultra-Stable Low TC Ultra-Precision Film Resistors were developed to meet the requirements for increasing performance for resistors in high performance analog electronics. Utilizing Caddock proprietary resistance film systems, the Type USF resistors provide the Lowest TC with the Widest Resistance Range and the Highest Voltage Ratings available in the industry.
* Resistance Range 50 ohm to 25 Megohm.
* Temperature Coefficient -40°C to 85°C, referenced to 25°C
200 Series -- ZERO Nominal TC -- Maximum Absolute TC 2 ppm/°C
300 Series -- ZERO Nominal TC -- Maximum Absolute TC 5 ppm/°C
* Tolerance: ±0.01% or ±0.10%.
* Specific standard resistance values are available that are most
commonly required in high accuracy analog design. These values
were selected and optimized for produceability and performance.
* 300 Series "matched pairs" are available with ratio TC as tight as
0.5 ppm/°C. Contact Applications Engineering.
* Ceramic package provides cool operation.
Type USF Ultra-Stable Resistors are offered in standard resistance values
that are most commonly used in precision analog design. These standard resistance values can be used in precise amplifier gain setting, precise resistor bridge circuits, precise transducer sense circuits, and precise voltage dividers with up to 2500 volt input voltage.
