Through Hole Resistors have been in use as a reliable and relatively low-cost form of electrical resistance or impedance since the 1950s. FKN5WSJR-73-10R, an axial leaded resistor,or through hole resistor, is a ubiquitous linear resistive component; it has a wide range of applications.

Applications

FKN5WSJR-73-10R is a general-purpose through hole resistor commonly used in electric circuits, such as amplifiers, oscillators and signal conditioning circuits. It is also used to regulate the current in power supplies or control various types of motor speed. It is widely used in AC/DC and DC/DC power supplies, automotive, industrial, consumer products, measurement equipment and control applications.

Construction and Working Principle

FKN5WSJR-73-10R is constructed on a solid substrate smeared with doped resistor material such as Carbon- or Metal Film, surrounded by insulating material. It comprises two cores, an outer core and an inner core, each having a set of coils wound around it. A connection is made between one of the cores and the substrate by a lead. The two cores interact with each other electro-magnetically, generating an electrical resistance in FKN5WSJR-73-10R. The resistor has two leads, each connected to a core, which establishes a circuit between the two cores.

The operating principle of FKN5WSJR-73-10R is based on the fact that electricity flowing through a coil wrapped around a core creates a magnetic field around the core. When an external field is applied to FKN5WSJR-73-10R, this induces a current in the coil, which in turn generates a magnetic field in the core, thus, creating an electrical resistance. The electrical resistance of FKN5WSJR-73-10R varies with the amount of current flowing through the resistor and the amount of external magnetic field present.

Advantages

FKN5WSJR-73-10R offers many advantages over other types of resistors, such as low electrical noise, relatively low power consumption, high frequency response, good temperature stability, high precision in resistance values, and good stability over time. Its low power consumption makes it suitable for applications where low power is an important consideration. Furthermore, since each turn of the coil contributes to the resistance, FKN5WSJR-73-10R can offer a wide range of resistance values and provides good accuracy and precision.

Disadvantages

The main disadvantage of FKN5WSJR-73-10R is that its resistance is dependent on both the operating frequency of the circuit and the magnetic field which is applied to it. This means that the resistor can be affected by external magnetic fields, such as those produced by electricity transmission lines, generators, motors, etc. This can lead to stability issues and inaccuracies in the readings. Additionally, since the resistor is a static component, its resistance value can not be changed after it is installed in the circuit.

Conclusion

FKN5WSJR-73-10R is a type of through hole resistor with a wide range of applications due to its low power consumption, high performance, and accuracy. This type of resistor is used in DC/DC and AC/DC power supplies, automotive, industrial, consumer products, measurement equipment, and control applications. However, one disadvantage of FKN5WSJR-73-10R is that its resistance can be affected by external magnetic fields, thus, requiring extra care in installing the resistor in the circuit.
