Trimmer Potentiometers are essential components for automated systems, as they are used for high-precision adjustment and fine-tuning. They are also commonly used in automatic voltage regulators (AVRs), displacement sensors, and other types of analog circuits. This article provides an overview of the application field and working principle of the 25SR200LF Trimmer Potentiometer.

The 25SR200LF is a single-turn trimmer potentiometer with a low temperature coefficient of variation, which makes it highly accurate and reliable for its intended purpose. It has a resistance value of 200 ohms, and the precision of adjustment is 0.2%. This trimmer potentiometer is most commonly used for circuit adjustment and fine-tuning in analog circuits, such as Automatic Voltage Regulators, Displacement Sensors, Differential Pressure Sensors, and other types of analog circuits. It can also be used to adjust the frequency of radio signals. The 25SR200LF is available in two mounting styles: through-hole and surface mount.

The working principle of a trimmer potentiometer is quite simple. When the user rotates the knob, the resistance of the potentiometer is adjusted, and the current through the circuit changes accordingly. The amount of resistance adjustability depends on the rotary switch, which is set to a certain maximum turn. Depending on the circuit, the user can zero in on a specific resistance value more precisely by aligning the pointer to the desired marker.

The 25SR200LF Trimmer Potentiometer is designed for precise and reliable operation, even in extreme environments. The sensitive spring mechanism allows for precise adjustment with minimal backlash, while the sealed construction makes it highly resistant to dust and moisture. The heat-resistant plastic housing is designed to withstand temperatures up to 125°C, ensuring effective operation in extreme conditions.

The 25SR200LF is an ideal choice for professional applications where precise adjustment and tuning of analog circuits is required. It is available in a variety of sizes, and its low profile makes it easy to use in tight spaces. This trimmer potentiometer is RoHS compliant, and meets the safety and performance standards of UL 1043/CSA C22.2 No. 223.

In conclusion, the 25SR200LF Trimmer Potentiometer is a reliable and precise component for fine-tuning analog circuits. It is widely used in a variety of applications, such as Automatic Voltage Regulators, Displacement Sensors, Differential Pressure Sensors, and other types of analog circuits. Its durability and performance in extreme conditions make it a great choice for a variety of industrial and commercial applications.
