The 3312J-1-100E is a 2 mm SMD Trimpot® trimming potentiometer designed for surface-mount manufacturing processes with a sealed, miniature form factor. It features a standard resistance range from 10 ohms to 2 megohms with ±20% tolerance, adjustability of ±0.4% in voltage divider mode and ±0.8% in rheostat mode, and an adjustment angle of 255° nominal. The device operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.1 watt at 70°C (50 volts maximum). Its compact design, RoHS compliance, and sealed construction make it ideal for precision trimming applications in instrumentation, signal processing, and calibration circuits where reliability and miniaturization are essential.
