Through Hole Resistors are used in a wide variety of electronic circuits for controlling current and voltage. The CMF551M2000JNRE is a three-terminal resistor which is constructed in an axial form, meaning it has two leads that extend outward in opposite directions from its body. This type of resistor is also known as a “Through Hole” resistor due to the fact that the two leads can be fitted into holes that are drilled into the board.

The CMF551M2000JNRE is commonly used in applications such as motor speed control, impedance matching, bridge rectifier circuits, and voltage sensing. It provides resistance (R) which can range from 0.5 ohm to 1 Megohm. The resistor features a power rating of 0.5W and its temperature coefficient ranges from -450ppm/K to -700ppm/K.

The working principle of the CMF551M2000JNRE is based on the fact that when the current inside the resistor is flowing, resistance forces the flow to become slower. This slower flow dissipates most of the current and produces heat that is conducted through the resistors own leads and to the board (or heat stock) where it can be dissipated.

The way in which the resistor works is relatively simple. When an electric current is passed through the resistor, its resistance prevents a portion of the current from passing through it. As a result, only a portion of the current actually makes it through the resistor and the remaining portion of the current is dissipated as heat. Since heat is dissipated at a much higher rate than current, the resistor is able to prevent the current from flowing through it at a rapid rate, thereby controlling the voltage and current levels in the circuit.

In addition, the resistor\'s body is designed with various insulating materials to ensure that much of the heat is conducted through the resistor and not through the board. The resistor also features a strain relief specification to ensure that long-term use will not create any additional stress on the board.

In conclusion, the CMF551M2000JNRE is a useful component for controlling current levels and voltage in various electronic circuits. It is constructed in an axial-form, making it suitable for fitting into through hole boards. This type of resistor can be used in a variety of applications, including motor speed control, impedance matching, bridge rectifier circuits, and voltage sensing, and provides a 0.5 ohm to 1 megohm range in resistance. Finally, due to its insulated body and strain relief specification, it is able to provide reliable performance even when exposed to long-term usage.
