The 3057Y-1-101 is a Trimpot® trimming potentiometer featuring a 1-1/4" rectangular multiturn wirewound design with sealed industrial construction. It offers a standard resistance range of 10 to 50K ohms with ±5% tolerance, 22 turns nominal adjustment travel, and a power rating of 1 watt at 70°C. The device operates reliably across a temperature range of -55°C to +150°C with a temperature coefficient of ±50 ppm/°C, and provides 1,000 megohms minimum insulation resistance at 500 VDC. The 3057Y style features compact lead dimensions (0.028 ± 0.001" diameter) and is RoHS compliant, making it suitable for precision trimming applications in industrial electronics, instrumentation, and control systems where reliable adjustment and environmental sealing are required.
