Through Hole Resistors are among the many types of resistors being used in the 21st century. One of the most popular and widely used examples of a through hole resistor is the 43F18RE, which has a wide array of applications and is currently being used in multiple industries. This article will discuss the application fields and working principle of the 43F18RE resistor.

General Information

The 43F18RE is a through hole resistor, which means it has a single hole through its middle for attaching the leads. This type of resistor is also known as an axial resistor because the leads are placed in a line parallel to the resistor’s long axis. In terms of design, the 43F18RE consists of a ceramic body, a delicate wire winding, and two copper-plated pins. The ceramic body is encased in such a way that it forms an airtight, insulated chamber to protect the delicate wire winding from any external substances. Additionally, the copper pins that make up the resistor’s leads are plated to extend its lifespan, as well as to prevent corrosion and other environmental hazards. When assembled, the 43F18RE measures about 18mm in length and 4.3mm in width.

Application Fields

The 43F18RE is commonly used in many electronic and electrical devices due to its complex design and superior resistance qualities. Most notably, it is used as a voltage regulator in power supplies for computers, TVs, video game consoles, and other electronics. It is also regularly used in various types of audio equipment as a variable ceiling resistor, tone control resistor, and pitch detector. Additionally, the 43F18RE is commonly used in motor controllers, which require a variable resistor to act as a noise and interference filter. As a result, the 43F18RE can be found in many types of digital and analog products, ranging from consumer electronics to industrial machinery.

Working Principle

The working principle of the 43F18RE is to resist the flow of electric current, which it does via its intricate wire winding. This winding, which runs the length of the resistor’s ceramic body, is composed of many fine, intertwined strands of metal. These metal strands are coated to prevent corrosion and other elements from interfering with the current flow. When current is applied, electrons flow through these metal strands, generating friction and resistance. As a result, the current is slowed down, which in turn allows the resistor to act as a voltage regulator. The amount of resistance and voltage regulation the resistor creates depends on the size and composition of the resistor’s winding.

Conclusion

In conclusion, the 43F18RE is one of the most common and widely-used through hole resistors being used today. It is most often used as a variable ceiling resistor, tone control resistor, pitch detector, and voltage regulator, and is found in everything from consumer electronics to industrial machinery. Its working principle is based on an intricate winding of metal strands, which create resistance and friction when current is applied. With its array of application fields and superior design, the 43F18RE is an invaluable component in the world of electronics.
