The 3269W-1-501GLF is a 1/4" square SMD Trimpot trimming potentiometer manufactured by Bourns, designed for precision resistance adjustment in surface-mount applications. It features a stable, infinite-resolution cermet element with a 500-ohm resistance value and ±10% tolerance, capable of handling up to 0.25 watts at 85°C with a maximum voltage rating of 300 volts. The device operates reliably across a temperature range of -65°C to +150°C with a temperature coefficient of ±100 ppm/°C, and incorporates mechanical stops with a wiper idle feature and H-90 wiper configuration. With solderable pins, a maximum torque of 2.5 oz-in., and RoHS-compliant 100% tin-plated terminations, this trimmer is ideal for circuit calibration, signal conditioning, and tuning applications in consumer electronics, industrial equipment, and telecommunications systems.
