The 3540S-40-102L is a 10-turn, wirewound precision potentiometer with a resistance of 1 kΩ and a tolerance of ±5%. It is engineered for high precision, offering an independent linearity of ±0.25% and a maximum noise level of 100 ohms ENR. This component has a power rating of 2 watts at +70°C and is built for durability with a rotational life of 1,000,000 shaft revolutions. It operates reliably across a wide temperature range of -40°C to +125°C. The bushing mount design makes it suitable for panel-mounted controls in industrial equipment and instrumentation where precise and stable adjustments are critical.
