The 3306P-1-105 is a 6 mm round single-turn Trimpot trimming potentiometer manufactured by Bourns, designed for industrial and open-frame applications requiring precise resistance adjustment. This cermet-based trimmer features a resistance value of 1 megohm with a standard tolerance of ±25%, an adjustment angle of 215° nominal, and essentially infinite resolution for fine-tuning. The device operates across a temperature range of -25°C to +100°C with a temperature coefficient of ±250 ppm/°C, and is rated for 0.2 watts at 70°C with a maximum operating voltage of 100 volts. The potentiometer includes dust-resistant and splash-resistant covers, cross-slot adjustment options, and both horizontal and vertical mounting styles, making it suitable for circuit calibration, signal conditioning, and equipment tuning in industrial electronics, instrumentation, and consumer applications where reliable long-term performance is required.
