Product description: Precision Resistor ASTRO2 - wirewound

ASTRO2 precision resistors are designed for critical and demanding applications requiring high precision and stable resistance. Multi-chamber (bifilar) windings ensure low inductance for these wirewound resistors. During manufacture, the resistors are trimmed using a special aging process which increases long term stability. The windings and epoxy coating are specially selected to ensure the best temperature performance. Typical applications include instrumentation, laboratory equipment, current sensing and low power applications.

  • Temperature coefficients up to ±10ppm/°C (up to ±1ppm/°C on request)
  • Resistance sets up to ±0.001% and ± 0.5ppm/°C
  • Special lead wire bending on request
  • Very stable over time ±100ppm/year (on request in a very stable version with ±20ppm/year)
  • On request with Balco or platinum connectors for high TC values
  • On request in very high or low TC configurations from -20ppm/°C to +6000ppm/°C
