Trimmer Potentiometers are commonly used for application fields requiring discrete adjustable resistance with pinpoint accuracy. ST4ETA102 is no exception and belongs to the two-terminal potentiometers family offering fine adjustment in the range of typically 2k Ohms. These highly reliable devices are found in power consumption, control, and stabilization applications.

ST4ETA102 offers rotary resolution of 100 to 1000 turns, depending on the device. It exhibits very low linearity drift values ranging from ±20 ppm max. It is highly reliable, with an estimated life of 10,000 cycles, and can survive up to a 105°C of operation temperature. Its hard sealing ensures a good protection for harsh electrical and environmental conditions.

This versatile two-terminal potentiometer is designed with high quality materials and sophisticated technologies. It offers a wide range of adjustment values with minimal force. Its resistance can be adjusted over a wide range by an equipped knob. The user can set a range from 0.1 ohm to 10 ohm with a tolerance of up to 0.1ohms. The whole device is RoHS compliant and features a low contact resistance of 10 mOhms.

The working principle of ST4ETA102 is based on the same concept used in standard potentiometers. The rotation of the dial is mechanically linked to the wiper which moves along the resistive track of the device. This movement modifies the resistance between the wiper, or the slider, and the two opposite ends of the resistive track. Depending on the chosen adjustment, the voltage or current level is altered, allowing for precise control.

In addition, ST4ETA102 offers a unique advantage over standard potentiometers in terms of accuracy, providing fine control parameters with a resolution of 0.1 %. With such adjustment precision, the device is suitable for high precision, regulated applications. It can be used in a variety of devices, including voltage regulators, heaters, thermostats, motor controllers, and more.

ST4ETA102 provides excellent performance for application fields needing precise setting with minimal force. Its fine adjustment allows for better optimization of energy consumption and hence reduces the total cost of ownership. While these potentiometers are highly reliable and accurate, it is recommended to choose the device having the smallest range that can suffice the application needs.
