The 3314J-1-504E is a 4 mm square Trimpol® trimming potentiometer designed for surface-mount applications in industrial sealed environments. This single-turn cermet device features a resistance value of 500 kO with ±20% standard tolerance and infinite resolution, providing precise voltage adjustment capabilities. It operates across a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and delivers a power rating of 0.25 watts at 70°C. The potentiometer includes a 210° nominal adjustment angle, 100 megohms minimum insulation resistance at 500 VDC, and meets EIA/EIAJ/IPC/VECI SMD standards with AEC-Q200 Grade 1 qualification. Its J-hook configuration with single-slot adjustment, RoHS compliance, and compatibility with vacuum pick-and-place equipment make it ideal for automated manufacturing of precision control circuits in industrial instrumentation and consumer electronics.
