Ultra-Stable Low TC Precision High Voltage Resistors

The USG1105 series from Caddock are ultra-stable precision high voltage resistors. The resistance values available are 50MΩ and 75MΩ with a TCR of 10 ppm/°C or 20 ppm/°C and a tolerance of ±0.10% or ±0.20% depending on the resistance value required. The USG1105 series from Caddock uses the Tetrinox® resistance film system and was developed to optimise low temperature coefficient performance and long term stability performance.

• Ultra-stable precision high voltage axial leaded film through-hole resistors
• Resistance values available are 50MΩ and 75MΩ
• TCR of 10 ppm/°C or 20 ppm/°C depending on the resistance value required
• Tolerance of ±0.1% or ±0.2% depending on the resistance value required
• Temperature range -40°C to +85°C
• Maximum voltage rating 5KV
• Typical load life stability 0.025% per 1,000 hours
• Utilising Caddock’s Tetrinox® resistance film systems

The low TCR of the Type USG1105 resistors minimizes temperature related drift due to temperature gradients that may exist due to the placement of the resistor components in the high voltage assembly
