Description

The USF370 series from Caddock are ultra-stable low temperature coefficient (TCR) film resistors, with a resistance range of between 990KΩ and 10MΩ, low TCR of ±5 ppm/°C and with a tolerance of ±0.01% or ±0.1%. The USF370 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 990KΩ and 10MΩ
  • TCR of ±5 ppm/°C
  • Tolerance of ±0.01% or ±0.1%
