SM31B202 Trimmer Potentiometers

The SM31B202 trimmer potentiometer is a three-terminal, adjustable miniature (15mmX17mm) device which provides a precise, adjustable resistance in a small package. This trimmer potentiometer is mainly used in automotive, industrial, and medical applications.

Overview:

The SM31B202 trimmer potentiometer is a three-terminal, adjustable miniature device which provides precision adjustable voltage dividers and variable gain amplifiers. It has a three screw-adjustable system with an adjustable range of 0-100Ω and an adjustable shaft angle of 10-32°. It is constructed with a sealed plastic body and rubber feet for maximum reliability and durability.

Features:

This trimmer potentiometer is ideal for use in automotive, industrial, and medical applications. It features low resistance, high stability, and excellent life. The SM31B202 is designed for surface mount applications and has a 5.08mm wide footprint. It uses a low-resistance, non-inductive process for maximum performance. Additionally, the SM31B202 is RoHS compliant and is lead (Pb) free.

Applications:

The SM31B202 trimmer potentiometer can be used for a variety of applications including adjusting circuit gains, voltage dividers, and bias settings in various automotive, industrial, and medical electronics. It is also ideal for calibration purposes, as the adjustable range allows for precise settings.

Working Principle:

The SM31B202 trimmer potentiometer consists of three terminals: a “L” terminal (Low), an “R” terminal (Resistor), and a “H” terminal (high). The “L” terminal is connected to ground, while the “R” terminal is connected to the resistance element. The “H” terminal is connected to the adjustable tap on the resistance element and serves as the output. The adjustable shaft is used to adjust the tap position on the resistance element, thus changing the output voltage.The SM31B202 trimmer potentiometer is a three-terminal, adjustable device which provides a precise, adjustable resistance in a small package. It is ideal for use in automotive, industrial, and medical applications due to its low resistance and high stability. It is also RoHS compliant and lead (Pb) free. The SM31B202 trimmer potentiometer consists of three terminals: Low, Resistor, and High. The adjustable shaft is used to adjust tap position on the resistance element, thus changing the output voltage.
