The SM-3TW201 is designed for a wide range of applications, including AC/DC stabilizer, audio preamplifier, transceiver, RF signal generator, automotive, telecom, and medical equipment.

Features and advantages

The SM-3TW201 trimmer potentiometer offers a number of features and advantages. It has a wide resistance range from 50 Ω to 1 MΩ and is ideal for automated assembly with applicable reflow equipment. The dimensions are a mere 6.3 x 1.5 x 0.6 mm, making it one of the smallest trimmer potentiometers on the market. Its low profile of 0.55 mm gives it a superior look when mounted on a PCB. The trimmer can also handle peak voltages of up to 30V and has strong insulation between all its conductors. With a linear taper, the SM-3TW201 provides precise linear outcome adjustment.

Application fields

The SM-3TW201 trimmer potentiometer is designed to be used in applications where small size, high accuracy, and stability are essential. It can be used in motor speed control systems and precision instrumentation. It is also suitable for use in telecommunications equipment, medical devices, and navigation applications. Other areas of application include electric power amplifiers, active filters, temperature and process controllers, and high-frequency signal generators.

Working principle

The SM-3TW201 trimmer potentiometer is a 3 terminal device that works on the principle of voltage division. It consists of a resistor element and a movable wiper that moves across the resistor to adjust the value of the resistance. The resistance is adjusted by turning the knob or sides of the SM-3TW201. The wiper is connected to one of the two outer terminals and the resistance between the terminals is varied when the knob or sides of the potentiometer are turned.

The SM-3TW201 trimmer potentiometer is a versatile, reliable, and accurate device that is suitable for a wide range of applications. It is designed to provide precise and reliable performance in challenging environments. The small size, high accuracy, and low profile of the SM-3TW201 make it an ideal choice for miniature equipment and demanding applications.
