CSM-largeVishay Precision Group's CSM series feature an all-welded construction made up of a Bulk Metal® resistive element with 60/40 tin/lead-plated copper terminations. Vishay's Bulk Metal technology enables the new wirewound resistors to provide superior TCR performance over larger, competing devices, as well as excellent long-term stability and ultra-precision tolerances down to ±0.1%.

Features & Benefits:

  • Power rating: 1 W to 3 W
  • Resistance tolerance: ± 0.1 %
  • Resistance range: 1 mΩ to 200 mΩ
  • Load life stability to ± 0.2 % (70 °C, 2000 h at rated power)
  • Short time overload: ± 0.1 % typical
  • Thermal EMF: 3 μV/°C (DC offset error, significant for low values)
  • Maximum current: up to 54 A
  • Proprietary processing techniques produce low TCR, tight tolerance and improve stability

Applications:

  • Switching and linear power supplies
  • Power management systems
  • Power amplifiers
  • Medical and automatic test equipment
  • Satellites and aerospace systems
  • Commercial and Military avionics
  • Test and measurement equipment
