The 3290H-1-202 is a 3/8" square Trimpot® trimming potentiometer designed for industrial applications requiring precision adjustment and reliability. This multiturn wirewound device features a sealed construction with 25 turns of adjustment travel, supporting standard resistance values from 10 to 50 kO with ±5% tolerance and a maximum noise specification of 100 ohms ENR. The potentiometer operates across a wide temperature range of -65°C to +150°C with a temperature coefficient of ±50 ppm/°C, delivering 1.0 watt power rating at 85°C and maintaining 1,000 megohms minimum insulation resistance at 500 VDC. Its robust design includes 30 G vibration and 100 G shock resistance, 200-cycle rotational life, and compliance with MIL-R-27208 and MIL-R-39015 standards, making it ideal for precision tuning applications in industrial control systems, instrumentation, and sealed electronic assemblies.
