Bourns’ Model 3312 2 mm sealed single-turn trimming potentiometer (trimmer) offers resistance values of 10, 20 and 50 ? over an operating temperature range from -55°C to 125°C. The device exhibits standard resistance toleratce of ±20%, voltage divider adjustability of ±0.2%, rheostat adjustability of ±0.4% and adjustment angle of 240° nom. over a resistance range from 10 ? to 2 M?. The trimmer presents power ratings of 0.1 W (70°C) and 0 W (125°C) at 50 V max., temperature coefficient of <100 ? ±150 ppm/°C and >100 ? ±100 ppm/°C, and rotational life of 25 cycles TRS ±3%. The component is suitable for hearing aids, bar code scanners, laser diodes, proximity switches, encoders, sensors and detectors, handheld machine tools, LCDs and touch screen systems, intercom systems and flow/temperature pressure measurement products.
