DESCRIPTION

The 3323W-1-202 is a Bourns miniature industrial single-turn trimming potentiometer featuring a 1/4" square cermet element with sealed construction for reliable performance in harsh environments. It offers a standard resistance range of 20 to 2,000,000 ohms with ±20% tolerance, infinite resolution, and adjustability specifications of ±0.05% for voltage and ±0.15% for resistance. The device operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and provides a power rating of 0.5 watt at 70°C with a maximum operating voltage of 300 volts. Its robust design includes a 240° adjustment angle, 270° mechanical angle, and meets stringent environmental standards including MIL-STD-202 humidity testing, 30G vibration, and 100G shock resistance. The 3323W-1-202 is ideal for automatic machine adjustment interfaces, industrial control systems, and applications requiring sealed, precision potentiometric tuning in demanding conditions.
