The 3545S-1-202L is a 5-turn precision potentiometer manufactured by Bourns, designed for high-accuracy analog control and measurement applications. It features a nominal resistance of 2,000 O with ±5% tolerance, independent linearity of ±0.25%, and an effective electrical angle of 1800° +10°, -0°, providing fine resolution of 0.044%. The potentiometer delivers 1.5 watts power rating at sea level, operates reliably across -55°C to +125°C storage and +1°C to +125°C operating temperature ranges, and maintains insulation resistance of 1,000 megohms minimum at 500 VDC. With bushing mount configuration, optional anti-rotation pin feature, and RoHS compliance, this precision potentiometer is ideal for instrumentation, servo systems, and precision control applications requiring stable, repeatable performance over extended operational life.
