SRT CRB 1210 Series

  • SRT Resistor Technology

Product Features

  • Trimmable non-magnetic, thick film chip resistor
  • Resistance range from 1Ω to 10MΩ
  • Tolerances from ±5% to ±30%
  • TCR from ±50 ppm/°C to ±250 ppm/°C
  • Power rating of 0.35W (at +70°C)
  • Temperature range from -55°C up to +155°C


The CRB 1210 non-magnetic, trimmable chip resistor series from SRT Resistor Technology offers a resistance range from 1Ω up to 10MΩ, power rating of 0.35W and voltage rating of 200V trimmed or 600V untrimmed (trimming ratios 3/single cut), all in a small 1210 surface mount package. By utilising SRT’s thick film resistor technology, they are able to offer low tolerances down to ±5.0% and TCR as low as ±50 ppm/°C (between 10Ω and 10MΩ). The CRB 1210 resistor series is suitable for laser and air-abrasive trimming, and offers PtAg (Platinum-Silver), unpassivated contact areas suitable for soldering and conductive gluing. These resistors contain no organics, making them suitable for high vacuum applications.
