Through hole resistors are an important part of modern electronics. One such type is the NKN500JR-91-0R39, which is generally used for limiting current or current-sensing applications, such as those found in cars and computers. In this article, we will explore the NKN500JR-91-0R39’s application field and working principle in detail.

The main purpose of a resistor is to reduce the amount of current, voltage, and power in an electric circuit. The NKN500JR-91-0R39 is a through-hole resistor, meaning that it is designed to be mounted on a circuit board. It has a power rating of 0.25 watts, and a resistance value of 1 ohms. This makes it suitable for limiting current or current sensing in low power circuits. For example, it can be used to limit the power flowing through a computer’s power supply, or to sense the current draw of the computer’s components.

The Working Principle of the NKN500JR-91-0R39

The NKN500JR-91-0R39 is a through-hole resistor, meaning that its leads are soldered directly to the board. When the leads are connected, current passes through the resistor, and is restricted by its resistance. As the current flows through the resistor, it builds up energy, which is then dissipated as heat. The resulting heat is proportional to the current, meaning that as more current flows, more heat is generated. This is known as Ohm’s Law, and can be used to calculate the resistor’s power rating.

Applications of the NKN500JR-91-0R39

The NKN500JR-91-0R39’s small size and low power rating make it suitable for a wide range of applications. For example, it can be used to limit the power draw of electronic appliances or components. It can also be used as a current sensor, allowing engineers to measure the current draw of an appliance or component. This can be useful for designing more efficient systems, as engineers can tailor their designs to match the current draw of the components.

The NKN500JR-91-0R39 is also used in automotive applications. It can be used to limit the power draw of the car’s electrical components, preventing them from drawing too much current and burning out. Additionally, it can be used to sense the current draw of components, allowing engineers to ensure that the car is not drawing too much current from its battery.

Conclusion

In conclusion, the NKN500JR-91-0R39 is a through-hole resistor, designed for limiting current or current sensing applications. Its low power rating and small size make it suitable for a wide range of applications, such as current-sensing in electronic appliances and automotive components. Finally, its working principle is based on Ohm’s Law, which states that current is proportional to the resistor’s power rating.
