Adjustable power resistors are essential components in many electronic circuits. From the point of view of application, they are mainly used in voltage and current detection, power device control, switching power supply control and constant current work system circuits. Their main function is to provide a feedback or control voltage signal to the external circuit for feedback or control. D175K15K adjustable power resistor is one of the most common styles of adjustable power resistors. It has a nominal resistance value that lies between15KΩ and 175KΩ.

The D175K15K adjustable power resistor is a three-terminal fixed resistor with a resistance range of 15KΩ to 175KΩ. Its characteristics include its large range within the rated range, linear resistance change, low drift, and high accuracy of its resistance value. These features make the adjustable power resistor well suited for many applications. The three-terminal adjustable power resistor contains three resistors connected in series, connected in the form of "MOS + R + R", and provides a large range of current detection and power regulation.

The working principle of the D175K15K adjustable power resistor is relatively simple. It contains three resistors connected in series, corresponding to the non-adjustable resistor MOS, the first adjustable resistor, and the second adjustable resistor. The two adjustable resistors operate together to give a resistance range from 15KΩ up to 175KΩ. The MOS is a non-adjustable resistor connected at the base of the two adjustable resistors. The resistance of this part of the resistor is fixed, and can be identified by its "T" code.

In the D175K15K adjustable power resistor, the two adjustable resistors form the “bridge” structure. One of the bridge’s adjustable resistors provides the lower half of the resistance range, while the other adjustable resistor provides the upper half of the range. When the adjustable power resistor is in operation, the two adjustable resistors are adjusted so that the total resistance value is within the range of 15KΩ to 175KΩ.

In addition to its resistance range, the adjustable power resistor also provides current regulation and voltage feedback. The two adjustable resistors are used to provide current resistance, to compensate for the output current fluctuations of the circuit, and to reduce power losses. The adjustable resistors also provide feedback for the control system, which allows the system to adjust the output power or voltage accurately. By detecting the voltage drop across the adjustable resistors, the control system can acquire the feedback, so that the feedback can control the output power of the circuit.

The D175K15K adjustable power resistor is a very effective and versatile component. It can be used in many different applications, from voltage and current detection, to power device control, to switching power supply control. It has a wide resistance range, and its combination of accuracy, stability, and feedback make it ideal for use in many circuits.
