Through Hole Resistors have been around for a long time, but the popularity of surface mount components has seen them become the dominant component type in recent years. Despite this, Through Hole Resistors still remain an important part of PCB design. The FKN1WSJR-52-1R1 Through Hole Resistor is one of the most common components available in the market today and offers several advantages over other types of resistors.

Construction

The FKN1WSJR-52-1R1 Through Hole Resistor is constructed using a 19mm or 7.56" diameter steel tube which is filled with a conductive material. This material, usually either resistive or conductive carbon, acts as the resistance element in the resistor. The resistor is then enclosed in an insulated outer container which is typically made from either plastic or epoxy which provides an additional layer of protection to the resistance element.

Application Field and Working principle

Through Hole Resistors are commonly used in a variety of applications including power supplies, signal conditioning, and voltage regulation. The resistor’s resistance is determined by the amount of material in the tube, with the most common being 1R, 2R, 4R and 5R. The resistor works by limiting the current flowing through it, which is determined by the amount of resistance provided. For example, if the resistor has a 1R resistance value, then it will limit the current to one ohm.

When using a Through Hole Resistor, the important thing to remember is that it can be used in high-current applications, such as power supplies and voltage regulators. This is because the high current capabilities of the resistor help to dissipate the heat from the resistor, thus creating a more efficient device. The most common application areas for the FKN1WSJR-52-1R1 Through Hole Resistor include automotive electronics, consumer electronics, computers, and communications.

Advantages

The primary benefit that Through Hole Resistors offer is their size and weight. Because they only need to occupy a fraction of the space of a traditional resistor, they are ideal for use in applications where space is at a premium. Additionally, Through Hole Resistors can also be more easily assembled onto a PCB since they do not require any special tools or procedures. Finally, the insulation around the resistor helps to reduce the risk of accidental contact, thus offering improved reliability.

Disadvantages

Though Through Hole Resistors offer a number of advantages, there are also several drawbacks that must be taken into consideration. The most obvious of these is cost, as Through Hole Resistors are generally more expensive than traditional components. Additionally, Through Hole Resistors are not as versatile as surface mount components which can be used in a wider range of applications. Furthermore, Through Hole Resistors are also more delicate than surface mount components, leading to increased maintenance and replacement costs.

Conclusion

The FKN1WSJR-52-1R1 Through Hole Resistor is a popular component amongst a wide variety of PCB designers, thanks mainly to its size, cost, and reliability. Despite the drawbacks associated with these components, their advantages far outweigh these drawbacks and make them an important part of any PCB design project. The FKN1WSJR-52-1R1 Through Hole Resistor can be used in both high current and low current applications, depending upon the requirements of the designer.
