A trimmer potentiometer, also known as a trim pot, trimmer, trimpot, preset, or adjustment pot, is a small variable resistor which is used for precision adjustment of electrical signals in circuits. The SM31B201 is a miniature trimmer potentiometer specifically designed for use in electronic and industrial applications.

The SM31B201 has a round knob structure, which allows for easy direct adjustment and is easy to use. This trimmer potentiometer is a single turn device, with 10 precision linear steps and a total adjustable range of 0-200 ohms. It offers a voltage rating of 3-50V DC, a power rating of 0.5W and a tolerance value of +/- 10%.

The SM31B201 is a versatile device that is suitable for use in a variety of applications. It is commonly used in muting, volume control, off-set adjustments, balance control, bias positioning and other applications requiring a wide range of electrical inputs. It is well-suited for use in active filters, amplifiers, and other related audio-related applications. It is also widely used in automotive, medical and industrial applications.

The working principle behind the SM31B201 is relatively simple. A small knurled wheel is connected to a resistive element which has two terminals. When the knurled wheel is twisted, the resistance changes on the resistor element. This change in resistance will then affect the amount of current that can flow through the device, resulting in a change in the output voltage.

To ensure reliable operation, the SM31B201 utilizes a patented slide ferrule construction technology which provides a superior terminal-to-shaft connection that is both highly reliable and robust. The device also features a protective seal which helps to protect against short-circuiting and environmental contaminants such as dust and moisture.

In conclusion, the SM31B201 is a miniature trimmer potentiometer specifically designed for use in electronic and industrial applications. It is well-suited for use in a variety of applications including muting, volume control, off-set adjustments, balance control, bias positioning and other applications requiring precision adjustment of electrical signals. The device is available with a voltage rating of 3-50V DC, a power rating of 0.5W and a tolerance value of +/- 10%. It uses a patented slide ferrule construction technology for a superior terminal-to-shaft connection and is protected with a protective seal to guard against short-circuiting and environmental contaminants.
