Through Hole Resistors (THR) are one of the most common passive components used in electronic circuits. The most essential THR components include fixed-value, variable, nonlinear, inverse, and wire-wound resistors. Most resistors used as loading devices, current limiting, and load balancing have an external structure, and their operation is based on Ohm\'s law. Typical THR used in applications include the CFR100JR-73-10M.

The CFR100JR-73-10M is a Through Hole Resistor (THR) based on a four-terminal construction. It can be used for various resistive elements in a wide variety of applications. The component consists of four resistive elements: The first two (A and B) are series-mounted and the two are in parallel. This type of series-parallel arrangement produces an overall resistance that is equal to the sum of two separate resistors. The resistor typically exhibits a flat resistance curve across its operating range. The resistor’s resistance is adjustable with a variable resistor that is connected to the two terminals (A and B).

The CFR100JR-73-10M has numerous applications as either a single-ended resistor or a dual-ended resistor. For single-ended applications, it can be used as a voltage divider, current sensing device, current limiting, and load balancing. In dual-ended applications, it can act as a nonlinear resistor, voltage divider, and current sensor. It is also used for thermal protection, load balancing, and EMI filtering.

The CFR100JR-73-10M also provides several advantages over other resistors. Due to its unique series-parallel configuration, it can provide a constant resistance over a wide temperature range. It is highly accurate and has exceptionally low temperature coefficients of resistance. Moreover, the variable resistor can be adjusted, which results in constant current levels and precise voltage control. Lastly, the component has a long life span and can be used in a wide range of high-frequency applications.

The working principle of the CFR100JR-73-10M is, in essence, based on Ohm\'s law. According to Ohm\'s law, the current supplied through a resistance is proportional to the voltage applied across it. Therefore, by adjusting the resistance of the component (which can be achieved with the variable resistor), the amount of current or voltage through it can be precisely controlled. In this way, various applications can be achieved depending on its set resistance.

In summary, the CFR100JR-73-10M is a Through Hole Resistor (THR) that provides a constant resistance across a wide temperature range. It has various applications such as voltage divider, current sensing device, current limiting, load balancing, and EMI filtering. Its working principle is based on Ohm\'s law, and its variable resistor allows precise control of current or voltage levels. As such, it is one of the most versatile and commonly used THR components.
