The 3682S-1-503L is a precision potentiometer from Bourns' 3680 family, featuring a 50 kO resistance value with 1% resolution and repeatable settings accurate to ±1.0% full scale. This decade potentiometer incorporates a digital display for excellent readability and snap-in panel mount design, with a dielectric withstanding voltage of 1,000 VAC minimum and power rating of 2 watts at +25°C. The device operates reliably over a temperature range of -25°C to +85°C, with an insulation resistance of 1,000 megohms minimum and rotational life rated for 75,000 button operations per decade. Its compact dimensions (26.67 mm × 25.15 mm) and low weight (16.5 grams) make it ideal for precision instrumentation, calibration equipment, and laboratory applications requiring accurate resistance adjustment with repeatable settings.
