The 3314G-1-501E is a 4 mm square Trimpot® trimming potentiometer manufactured by Bourns, designed for surface-mount industrial applications with sealed construction and RoHS compliance. This single-turn cermet trimmer features a 500 ohm resistance value with ±20% tolerance, infinite resolution, and an adjustment angle of 210° nominal, providing precise manual tuning capabilities. The device exhibits a rotational life of 100 cycles with ±3% tracking resistance stability, a maximum torque of 180 g-cm, and operates reliably across industrial temperature ranges with 500 VDC insulation resistance (100 MO minimum). The gull-wing pin configuration is compatible with popular vacuum pick-and-place equipment and surface-mount manufacturing processes, meeting EIA/EIAJ/IPC/VECI SMD standards and AEC-Q200 Grade 1 qualification. Common applications include precision circuit tuning, calibration adjustments, and industrial control systems where reliable, sealed potentiometer performance is essential.
