The 3314J-2-502E is a 4mm square Trimpot® trimming potentiometer manufactured by Bourns, designed for industrial sealed surface-mount applications with a 5 kO nominal resistance value. This single-turn cermet trimmer features a cross-slot adjustment mechanism and is compatible with standard surface-mount manufacturing processes and vacuum pick-and-place equipment. The device offers an adjustment angle of 210° nominal, infinite resolution, and meets EIA/EIAJ/IPC/VECI SMD standards with RoHS compliance and AEC-Q200 Grade 1 qualification. Key electrical characteristics include ±20% standard resistance tolerance, 1% or 2 ohms maximum end resistance, and 500 VDC insulation resistance of 100 megohms minimum. The trimmer is rated for 100 rotational cycles with ±3% total resistance stability, operates reliably under thermal shock (5 cycles), humidity (90-98% RH, 240 hours), and vibration (20 G) testing. Applications include precision circuit tuning in industrial equipment, consumer electronics, and automotive systems where compact, sealed adjustment is required.
