Through Hole Resistors

Through hole resistors are widely used in a wide variety of electronic projects, and are typically chosen for their low cost, high accuracy, and good stability over time. RWR89S3480FRS70 is an example of a through hole resistor, and in this article, we will explore its application fields and working principle.

Application Field

The RWR89S3480FRS70 is a through-hole resistor with high precision and a power rating of 0.125 W. It provides excellent temperature stability and is designed for use in industrial, automotive, and medical applications. It is also suitable for use in home electronic equipment due to its strong power and wide operating temperature range.

Given its high precision and wide operating temperature range, the RWR89S3480FRS70 is well-suited to circuit protection applications such as fault protection and overcurrent protection. It is also suitable for high-frequency applications, as it has a high self-resonance frequency.

In addition, the RWR89S3480FRS70 is also suitable for surface-mount applications, given its small size and its ability to handle high-power currents. It is also suitable for use in telecommunication, computer, and consumer electronics due to its small size, good stability, and low cost.

Working Principle

The working principle of the RWR89S3480FRS70 is based on the fact that it passes a certain current when a voltage is applied to it. The current passing through the resistor is proportional to the voltage applied, and this relationship is known as Ohm\'s law, which states that the current is equal to the voltage divided by the resistance.

The relationship between voltage, current, and resistance can also be expressed through an equation: I = V/R, where I is the current, V is the voltage, and R is the resistance. The RWR89S3480FRS70 uses a fixed resistance, so when a voltage is applied to it, the current passing through it will remain the same, and the voltage drop across the resistor will also remain the same.

In addition, the RWR89S3480FRS70 is designed with a high power rating and is able to handle high power currents without overheating. This is due to its robust construction, which is designed to withstand high temperatures and wide voltage and current ranges. The resistor is also designed to dissipate heat quickly to avoid overheating, and it is also designed with an insulated coating to reduce leakage current.

Conclusion

The RWR89S3480FRS70 is a through-hole resistor with high precision and a power rating of 0.125 W. It is suitable for use in industrial, automotive, and medical applications, as well as for circuit protection applications such as fault protection and overcurrent protection. In addition, it is suitable for use in telecommunication, computer, and consumer electronics due to its small size, good stability, low cost, and ability to handle high-power currents. The working principle of the RWR89S3480FRS70 is based on Ohm\'s law, and it is designed to dissipate heat quickly and maintain its resistance and power capacity.
