The CRA 0805 trimmable chip resistor series from SRT Resistor Technology offers a resistance range from 1Ω up to 10MΩ, power rating of 0.125W and voltage rating of 100V trimmed or 300V untrimmed (trimming ratios 1.5/single cut), all in a small 0805 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 CRA 0805 resistor series is suitable for laser and air-abrasive trimming, and offers Nickel-barrier/matte-tinned, glass passivated contact areas suitable for soldering. These resistors contain no organics, making them suitable for high vacuum applications.
