Introduction

Through Hole Resistor (THR) is a very important basic electronic component. It has wide applications in many areas such as circuit protection, power controlling, microelectronics, and other fields. In this article, we will focus on THR one of its specific examples – the CPR05R3900KE31 and discuss its application fields and working principle.

Application Field of CPR05R3900KE31

CPR05R3900KE31 is a non-surface mount type through hole resistor with a resistance value of 390 ohms. It is an ideal component for use in both AC and DC circuits, and is commonly used in automotive, appliance, lighting, telecommunication, and home audio applications.

Design and Working Principle of CPR05R3900KE31

The CPR05R3900KE31 has a narrow body and is compact in size. It is equipped with four solder pads for easy mounting. The component is encapsulated in epoxy to make it resistant to environmental conditions such as temperatures and humidity.The working principle of the component is simple. When the component is connected to a circuit, the resistance of the resistor induces a voltage drop. This voltage drop is necessary in order to maintain a predetermined voltage level across the circuit. The component regulates the current through the circuit such that the voltage level does not exceed the predetermined level.

Conclusion

The CPR05R3900KE31 is a through hole resistor with a wide range of applications. It is well-suited for both AC and DC circuits, and is most commonly used in automotive, appliance, lighting, and telecommunication applications. It is designed with a narrow body and four solder pads for easy mounting. Its working principle involves inducing a voltage drop across the circuit to maintain a predetermined voltage, thus regulating the current.
