An adjustable power resistor, also known as a rheostatic resistor, is a device which is used to control the amount of electric current flowing through a circuit. D50K20K is a type of adjustable power resistor which is popularly used in various applications, due to its wide variety of features and benefits. This article will discuss the D50K20K application field and working principle.

The D50K20K Application Field

The D50K20K resistor is mostly used in Automotive electronics applications such as Electronic Control Units (ECUs), Battery Management System (BMS), Driver Monitor Display (DMD) systems, and On-Board Diagnostic (OBD) components. The resistor is also used in various power electronic circuits, including Motor Drive circuits, Voltage Regulator Circuits, Power Line communication circuits, On-Board communication circuits, and Motor Starter/Control circuits. Additionally, the resistor is also used in consumer electronics components, such as home appliances, personal computers, and digital televisions.

Working Principle

The D50K20K adjustable power resistor works by providing a variable resistance to the electric current pass through it. The resistor is made up of two terminals which are connected to two different ends of a substrate material. By changing the distance between these two terminals, the resistance offered by the substrate material can be increased or decreased, thus allowing the electric current to be controlled. When the resistance is increased, the electric current decreases, and when it is decreased, the electric current increases.

The resistor has an adjustable voltage coefficient which can be changed by adjusting the distance between the two terminals. This voltage coefficient is used to regulate the amount of current that flows through the resistor. The resistance of the resistor is also adjustable, which allows it to be set to different levels for different applications.

The resistor has an adjustable power loss rating which is determined by its wattage rating. Based on this rating, the power loss of the resistor can be adjusted by increasing or decreasing the distance between the two terminals. The wattage rating can be increased to allow higher voltages to pass through the resistor.

The resistor also has an adjustable temperature coefficient which affects the amount of current that can be passed through it. By adjusting the distance between the two terminals, the temperature coefficient can be changed, which allows for different levels of current to be used. This can be useful in applications where the temperature can vary significantly.

Conclusion

The D50K20K adjustable power resistor is a versatile device which is used in a variety of applications, due to its wide variety of features and benefits. The resistor can be adjusted to different resistance levels, power losses, and temperature coefficients, allowing it to be used for a wide range of applications. Additionally, the resistor has an adjustable voltage coefficient which can be used to regulate the amount of current that flows through it, making it suitable for use in applications where voltage levels need to be controlled.
