Caddock USF340 Series

Caddock USF340 Series

The USF340 series from Caddock are ultra-stable low temperature coefficient (TCR) film resistors, with a resistance range of between 50Ω and 20MΩ, low TCR of ±5 ppm/°C and with a tolerance of ±0.01% or ±0.1%. The USF340 are constructed with an aluminum oxide ceramic sandwich which provides great thermal conductivity which very effectively minimizes the power coefficient drift. Utilising Caddock proprietary resistance film systems, they provide the lowest TCR and the highest voltage ratings available in the industry.

  • Ultra-stable radial leaded film through-hole resistors
  • Resistance values available are between 50Ω and 20MΩ
  • TCR of ±5 ppm/°C
  • Tolerance of ±0.01% or ±0.1%
  • Operating temperature -40°C to +85°C
  • Maximum working voltage of 300V
  • Ceramic package provides cool operation
  • Maximum power rating of 0.33W at +85°C
  • Utilising Caddock's proprietary resistance film systems

The USF Ultra-Stable Resistors are offered in standard resistance values that are most commonly used in precision analog design and can be used in

  • Precise amplifier gain setting
  • Precise resistor bridge circuits
  • Precise transducer sense circuits
  • Precise voltage dividers with up to 2500 volt input voltage
