Through Hole Resistors are one of the most common and popular components in any electronic device. A through hole resistor, commonly known as a through-hole component, is a component that is placed through a board or substrate and soldered to create a connection. A through-hole resistor is used to reduce the amount of electric current passing through a circuit, or to lower the voltage across a circuit. The LR2F47K is an example of a through hole resistor and its application field and working principle are explained in this article.

The LR2F47K through hole resistor has a power rating of 2 Watt and a resistance range of 0.10Ω - 0.56Ω. It features a tolerance of ±5%, a surge capability of 70A, and a temperature coefficient of -5500 to +2500 ppm/°C. This resistor is designed and manufactured to withstand high current and voltage surges as well as high-temperature applications. Its mounting hardware can be selected to match with most types of through hole components, allowing for easy installation in any type of electronic device.

The LR2F47K through hole resistor has a wide range of applications. It can be used as an energy source or energy absorbing component in the power system of different electronic products. It is commonly used as a voltage reduction device in an automotive system, to reduce the voltage, so that the current does not exceed the device’s power rating. In some cases, it is also used as a frequency reduction device, by using different capacitance values. It is also used in heating and air-conditioning systems, to reduce the voltage and maintain a steady temperature.

The working principle of the LR2F47K through hole resistor is based on Ohm’s law, which states that electricity always follows the path of least resistance. When a current is applied to the resistor, electric current is generated through it, as it has an inherent resistance value. The generated electric current is a function of the voltage applied and the resistor’s resistance value. In addition, the current is also a function of temperature. The resistor dissipates energy in the form of heat, which needs to be carefully monitored, as these components can overheat and fail if not properly managed.

In summary, the LR2F47K is a through hole resistor with a power rating of 2 Watt and a resistance range of 0.10Ω - 0.56Ω. It has a wide range of applications, as it can be used as an energy source or energy absorbing component and as a voltage and frequency reduction device. Its working principle is based on Ohm’s law, enabling an electric current to be generated through the resistor with the applied voltage and the resistor’s resistance value. Care needs to be taken in managing the heat generated, as these components can overheat and fail if not properly managed.
