Caddock TG Series

Caddock TG Series
The TG series from Caddock are low TCR precision high voltage resistors, with a resistance range between 1MΩ and 1,000MΩ. They have a tolerance of ±1.0% (down to ±0.1% on special order) and the low TCR value is ±25 ppm/°C (between -55°C and +125°C). The TG series utilize Caddock's proven Tetrinox® resistance system to achieve the unique combination of low temperature coefficient (TCR) which minimizes the self-drift due to power dissipation warm-up and high stability performance at high operating voltages.
  • Precision high voltage axial leaded through-hole resistor
  • Resistance values available between 1MΩ and 1,000MΩ
  • TCR of ±25 ppm/°C (between -55°C and +125°C)
  • Tolerance of ±1.0% (down to ±0.1% on special order)
  • Maximum power rating of 6W (model dependent)
  • Load life stability to 0.25% per 1,000 hours at +125°
  • Maximum continuous operating temperature of +225°C
  • Maximum operating voltage from 4kV up to 30kV (standard series)
  • Utilises Caddock's Tetrinox® resistance technology
  • The -15 series increases the maximum voltage ratings by 60% (48kV for the TG1015 model)
