Trimmer Potentiometers

A trimmer potentiometer, also known as a trimpot, is an adjustable, three-terminal, linear or circular potentiometer used for adjusting resistance in circuit boards. These devices are widely used when precise adjustments are necessary in electronics circuits.The ST4EH104 is a trimmer potentiometer manufactured by Susumu Electronics, which features both linear and rotary configurations. It is enclosed in a miniature SOT-23 package and is perfect for use in compact devices, such as cameras and use in mobile phones. The potentiometer is highly durable, featuring a rated resistance rating of 0.2 W and an operating temperature range of -55°C to +125°C.

Application Fields

Trimmer potentiometers are typically used when precise resistance adjustments are required. They are commonly used in audio and video equipment, as well as many types of industrial controls and motion control systems. Additionally, trimmer potentiometers are often used in educational experiments and research projects.The ST4EH104 trimmer potentiometer is suitable for use in game controllers, computer peripherals, LCD displays, telephones, office automation systems, test equipment, printer and scanner modules, digital cameras, and any other device which requires precision adjustments.

Working Principle

Trimmer potentiometers are typically connected in series with the rest of the circuit. By adjusting the slider, the resistance of the potentiometer can be adjusted. This adjustment changes the current flowing through the potentiometer, which in turn affects the voltage output. This adjustment also changes the resistance in the circuit, allowing for precise adjustments in the current.The ST4EH104 is a surface mount device with a precision resistance of 1kΩ. This potentiometer is designed to be mounted on a circuit board and manually adjusted using a thin screwdriver or other tool. This device is constructed from high-precision ceramic elements, and is highly reliable and resistant to vibration and shock.

Conclusion

Trimmer potentiometers are essential components in many circuits due to their precision and adjustability. The ST4EH104 is a popular choice for use in small circuits due to its miniature SOT-23 package. The ST4EH104 is suitable for game controllers, computer peripherals, LCD displays, telephones, office automation systems, test equipment, printer and scanner modules, digital cameras, and many other applications. Its high accuracy and reliability make it perfect for precision adjustments.
