Trim pots, or trimmer potentiometers, are adjustable resistor devices that allow a technician to calibrate or adjust an analog system. TM7EP104 is a precision Trim Pot, and its main application field and working principle will be discussed in the following paragraphs.

TM7EP104 is mainly used in analog circuit, including bridge circuits, switching detection circuits and so on. As a potentiometer, it provides an adjustable resistance that can be used to fine-tune a circuit’s operation. It is designed for AC and DC operation and can be used in a variety of circuits.

The working principle of the TM7EP104 is quite simple. It is composed of three conductive layers. The middle layer is the one with the variable 100 kΩ resistance. The upper and lower layers are the connection points to the external circuit. By connecting the two outer connections, a resistance is created in the middle layer. This resistance value can be adjusted by applying a current through one of the outer connections. This current is then passed through the middle layer, changing the resistance between the two outer connections.

The TM7EP104 also has a unique feature, which is the Track and Hold Function. This allows the leg to remain at its current position even when the adjust current is disconnected. This allows for more accurate adjustment of the resistance without having to repeat the process each time the current is disconnected.

One of the benefits of using TM7EP104 in analog circuit applications is that it can reduce the effects of environmental noise and interference. This is because the resistance between the two outer connections is only affected by the adjustment current and is not affected by other outside interference, such as electrical noise or temperature changes.

In addition to reducing noise interference, TM7EP104 also offers much more precise and reliable adjustment of the resistance between the two outer connections. This is because the resistance is changed before the circuit is connected to an outside circuit, which means that the final resistance value is much more predictable than with other types of trimmers.

In conclusion, TM7EP104 is a precision Trim Pot that is mainly used in analog circuits. Its main application field is bridge circuits, switching detection circuits, etc. Its working principle is quite simple, and it is composed of three layers, two of which are the external connections and one is the adjustable resistance layer. One unique feature of TM7EP104 is its Track and Hold Function, which allows the leg to remain at its current position even when the adjust current is disconnected. The main benefit of using TM7EP104 is that it offers much more reliable and precise adjustment of the resistance between the two outer connections, which can reduce noise and interference in the circuit.
