DESCRIPTION
The 3290H-1-203 is a 3/8" square Trimpot® trimming potentiometer designed for industrial applications requiring precision resistance adjustment. This multiturn wirewound device features a sealed construction with 25 turns of adjustment travel, standard resistance tolerance of ±5%, and a resistance range of 10 to 50 kO. It operates reliably across a wide temperature range of -65°C to +150°C with a power rating of 1.0 watt at 85°C, and meets military specifications (MIL-R-27208 and MIL-R-39015) with RoHS compliance. The potentiometer exhibits excellent electrical characteristics including 1,000 MO minimum insulation resistance at 500 VDC, dielectric strength of 1,000 VAC at sea level, and low noise of 100 O ENR maximum. Common applications include circuit calibration, signal conditioning, and equipment tuning in industrial control systems, telecommunications, and test instrumentation where sealed, multiturn adjustment is required.
