Through Hole Resistors are used to introduce resistance into circuits to control current flow, to regulate voltage, to protect circuits from surges, and to compensate for circuit tolerances. The MFR100FTF73-27K4 is a 4-pin, through hole resistor that is commonly used in industries such as telecom and automotive.

There are several differences in the construction of this resistor compared with standard through hole resistors. Firstly, it uses soft substrate material, which makes it more suitable for applications that require tight tolerances and precise temperature coefficient of resistance (TCR) performance. In addition, the MFR100FTF73-27K4 incorporates a tight tolerance film layer with an internal stress balance technology that helps to improve stability and reduce internal thermal stress.

The MFR100FTF73-27K4 is typically employed in telecom applications, such as in DSL modems, xDSL modems and other related telecom equipment. Because of its high precision, high performance, wide temperature range and high reliability, the MFR100FTF73-27K4 is also suitable for use in automotive applications such as power supply, brake systems, and exhaust emissions.

In terms of its working principle, the MFR100FTF73-27K4 controls the current in a circuit by providing a known resistance in the path of the current. This is accomplished by the intrinsic properites of the resistor material, usually carbon or metal. When a current enters a resistor, its molecules react to the electrical charge, and due to this resistance, the current is limited by a voltage drop across the resistor.

The MFR100FTF73-27K4 also features a 4-pin construction that provides additional features, such as surge protection and current limiting. The two pins on one end of the resistor can be used to limit the current flowing through it to a set level, while the two pins on the other end can be used to protect against overvoltage.

Overall, the MFR100FTF73-27K4 is a 4-pin, through hole resistor that is highly suitable for use in telecom and automotive applications. Its construction utilizes soft substrate material and tight tolerance film layers, which provide tight tolerances and precise temperature coefficient of resistance (TCR) performance. Moreover, the 4-pin construction allows for additional features such as current limiting and surge protection. Finally, it works by limiting current through the resistor due to its intrinsic properties and voltage drop across it.
