Description

The USF270 series from Caddock are ultra-stable low temperature coefficient (TCR) film resistors, with a resistance range of between 990KΩ and 5MΩ, low TCR of ±2 ppm/°C and with a tolerance of ±0.01% or ±0.1%. The USF270 are constructed with two selected USF300 series resistors bonded back to back for parallel connection on the PCB and using a ceramic package provides cool operation. 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 5MΩ
