A trimmer potentiometer is an electronic component with three terminals. Also called a trim pot, trimpot, preset, or variable resistor, it works by adjusting the electrical resistance between two of its terminals when the third is turned. Trimmer potentiometers are often used to calibrate and fine-tune the performance of electronic circuits and systems.

ST7EA102 is a small-sized trimmer potentiometer, often used in sophisticated and critical electronic equipment such as mobile phones, notebook computers, cameras, automotive, and industrial control systems. With a footprint of just 5x7 mm, the ST7EA102 can still provide reliable performance and durability, and is capable of operating between -40 and +85 degrees Celsius.

The ST7EA102 is a single-turn, linear trimmer potentiometer. Its simple, three-terminal construction consists of a wiper, A terminal, and B terminal. Each type of terminal has its own specific purpose. In a nutshell, the wiper is responsible for the varying resistance between the two other terminals; in ST7EA102’s case, the A terminal is attached to the adjustment screw, while the B terminal is connected to ground. To control the resistance variation, a user rotates the screw. The number of turns to reach the desired resistance can be adjusted in the factory, allowing users to adjust it accordingly.

The ST7EA102 is a reliable choice when it comes to producing low-cost, precise, and well-controlled electronic control systems. Furthermore, it is an excellent choice for bulk-manufactured products that require precise control of power supplies.

In addition to power supply control systems, ST7EA102 trimmer potentiometers may be used in a variety of electronic devices and circuit designs. It can serve as a voltage divider for circuit designs in communications systems, amplifiers and filter circuits, or as a DC serially adjustable potentiometer in high-current circuits. Other applications for which the ST7EA102 is used include audio control, timer circuits, remote control systems, temperature controls, and feedback systems.

The ST7EA102’s wide operating temperature range and reliable performance make it a great choice for both production and prototypes. It is a reliable and cost-effective option for many different kinds of control systems. This trimmer potentiometer is widely used in sophisticated and critical electronic equipment.
