The 3306P-1-502 is a 6 mm round single-turn cermet trimming potentiometer manufactured by Bourns, designed for industrial and open-frame applications requiring precision resistance adjustment. This model features a 5 kO resistance value with ±25% standard tolerance, an adjustment angle of 215° nominal, and a mechanical angle of 260° ±20°. The potentiometer operates over a temperature range of -25°C to +100°C with a temperature coefficient of ±250 ppm/°C, and is rated for 0.2 watt at 70°C with a maximum operating torque of 4.5 oz-in. The device includes dust-resistant and splash-resistant covers, cross-slot adjustment options for both horizontal and vertical mounting, and solderable pins for reliable PCB integration. It is RoHS compliant and commonly used in instrumentation, signal processing, and equipment calibration where precise resistance tuning is required.
