SRT CRB 1210

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.
