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.
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.
Extremely Low Power Coefficient (Wattage Coefficient):
resistors are constructed with an aluminum oxide ceramic sandwich
which provides great thermal conductivity. The ceramic sandwich
package very effectively minimizes the power coefficient drift. Power
coefficient is the resistance drift due to temperature rise in the element
caused by the power (wattage) dissipation in the resistor where the self-
heating temperature rise of the resistor element results in TC drift (temp.
rise in °C, times the temperature coefficient of the resistor). In the USF
package, heat is pulled away from the resistance material efficiently by
this ceramic sandwich package construction. Plastic molded Low TC foil
resistors cannot provide this outstanding benefit since the plastic impedes
the flow of heat, causing greater temperature rise at the resistor element
and greater self-heating related resistance drift due to power dissipation.
The USF 200 Series resistors provide a new level of performance with
near ZERO TC, very low power coefficient, wide resistance range, and
higher voltage ratings than is offered by other resistor technologies.
Absolute Tol. to ±0.01%, Resistance Range 50 Ohm to 25 Megohm, Voltage Ratings up to 2500 Volts
Model Number
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.
