LR1LJR15 Through Hole Resistors Overview

Through hole resistors (THRs) are one of the most commonly used types of resistors in electronics. They are comprised of two leads which extend from the body of the resistor, providing access for soldering or other electrical connection. The size to which the leads are available depends on the size of the device being used; while THRs typically come in sizes ranging from 0.1” to 0.8��, the LR1LJR15 THR is 5” in length.

The LR1LJR15 THR is a multi-purpose resistor capable of handling high power applications. Its use in designs is typically for power supply and power control applications, such as lighting and motor control circuits. The resistor is rated at a power rating of 600 watts continuous power dissipation. It has high resistance precision and stability over time, making it suitable for power supply designs that require accurate and reliable operation.

The LR1LJR15 THR has a wide range of applications that make it suitable for a wide variety of applications. It is capable of handling high power applications such as motor control, rectification, and in high frequency switching circuits. It can also be used in temperature monitoring systems, or for filtering, power supply bypass, current sense, and surge protection.

LR1LJR15 THR Working Principle

The working principle of the LR1LJR15 THR involves passing an electric current from one end of the resistor to the other. This current is affected by the resistance value of the resistor. As the current passes through the resistor, some of the energy is lost as heat due to the resistance of the resistor material. This heat is then dissipated into the surrounding environment.

The resistance value of the resistor changes as the temperature of the environment surrounding the resistor increases and decreases. This change, known as thermal coefficient, affects the current passing through the resistor. As the temperature rises, the resistance of the resistor increases, resulting in a decrease in the current passing through the resistor. Conversely, as the temperature lowers, the resistance decreases, resulting in an increase in the current passing through the resistor.

The LR1LJR15 THR is designed with a thermal coefficient of ±2.5%/°C. This compensates for any temperature-induced resistance change, ensuring the resistor stays within the specified power range at all times. As the temperature surrounding the resistor increases, the resistance of the resistor increases as well, resulting in a decrease in the current through the resistor. The opposite is true when the temperature of the surroundings decreases, resulting in an increase in the current through the resistor.

In addition, the LR1LJR15 THR has been designed with a wide operating temperature range of -40°C to +175°C. This ensures that the device is capable of operating over a wide range of temperatures, ensuring stable operation even in extreme temperatures.

Overall, the LR1LJR15 THR is a versatile and reliable through hole resistor. Its wide range of applications make it suitable for a variety of designs, and its high power rating and wide operating temperature range make it suitable for high power applications.
