Through Hole Resistors

Through Hole Resistors are a type of resistor that is used in many electronics applications and situations. The H8402RFAA is a highly popular, particularly for its high power handling capabilities and relatively low cost. In this article, we will discuss the application field and working principle of the H8402RFAA.

Applications

The H8402RFAA is a through hole resistor commonly used in power supplies. This type of resistor helps to reduce the amount of current that can pass though the supply. Not only does the resistor have a high power rating, but it also has a high surge current rating, which makes it very suitable for dealing with sudden increases in voltage. This makes it a popular choice for many industrial applications, as well as radio frequency applications, such as audio and video equipment.

Working Principle

The H8402RFAA works on a simple principle - it restricts the flow of electrons through the power supply. It does this by providing a physical barrier between the two terminals of the power supply. The electrons must pass through the resistor before they can reach their destination, and this restriction causes a drop in voltage, thus reducing the amount of current that can flow through the supply. The amount of current that can pass through the resistor is controllable - simply by adjusting the resistance of the resistor, you can control the flow of electrons. In this way, you can control the voltage of the power supply, and ensure that it stays within the acceptable range.

Pros and Cons

One of the main advantages of the H8402RFAA is its high power rating. It is capable of handling high currents, and it has a very low thermal coefficient, which means that it will not overheat easily. This makes it suitable for long-term use in high-power applications. In addition, the resistor is relatively inexpensive, meaning that it is an attractive choice for many applications.One disadvantage of the H8402RFAA is that it is a through-hole resistor. This means that it has to be attached to the circuit board with a soldering iron, which is sometimes inconvenient and difficult. In addition, because the resistor is through-hole, it will take up more space on the board, making it inaccessible in some applications.

Conclusion

The H8402RFAA is a versatile and useful through hole resistor, popular for its high power handling capability and low cost. It is used in various industrial and radio frequency applications, and its ability to control the flow of current makes it a valuable asset in maintaining power supply stability. While it is not always the most convenient option due to its through-hole nature, its relative low cost and impressive performance make it a valuable option for many projects.
