Description

The GR102 Squaristor radial wirewound precision resistor series from General Resistance offers ultra-precision and excellent long term stability over temperature and time, with a resistance range from 10Ω up to 200kΩ. The GR102 Squaristor series utilises the highest quality copper alloy drawn from melts of known resistivity and controlled temperature coefficients. The windings are balanced multiple π for low reactance. Together these enable the GR102 Squaristor series to have excellent noise levels and lower TCR of ±5 ppm/°C maximum (from -55°C and +125°C).

  • Wirewound radial leaded precision resistor
  • Available in any resistance between 10Ω and 200kΩ including custom values
  • Small radial leaded through-hole package
  • Wire gauge of 22AWG (0.6mm)
  • Excellent stability of ±35ppm/yr
  • Noise levels so small they are immeasurable
  • Tight tolerance options of ±0.01% (A) and ±0.1% (D) available for the full resistance range
  • TCR of ±5 ppm/°C maximum (from -55°C and +125°C)
  • Maximum working voltage of 150V
  • Power rating of 0.3W (at +85°C, GR102D model) and ≈0.18W (at +85°C, GR102A model)
  • Maximum rated operating temperature +85°C
  • Temperature range from -55°C up to +160°C

 

The GR102 Squaristor radial wirewound precision resistor series offers ultra-precision in a small compact radial leaded through-hole package, making them the ideal solution for test and measurement applications including test and calibration equipment.

Any custom resistance value between 10Ω and 200kΩ can be produced, with a low minimum order requirement of 10 pcs for non-standard parts (30 pc minimum order quantity for standard parts).
