Description
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.
