Chassis Mount Resistors: L25J3R0E application field and working principle

Chassis Mount Resistors are passive devices consisting of two contact terminals, two leads, and two resistive elements. These resistors are used to control the flow of electricity through a circuit. They are also used for a variety of purposes, including voltage regulation, signal conditioning, temperature compensation, and protection against over currents. The main purpose of the Chassis Mount Resistors is to limit the flow of electric current in a circuit.The L25J3R0E is a chassis mounted resistor and has unique features and advantages. It is a three-terminal chassis-mounted resistor with a low thermal stability, low noise and high current capacity. It is usually used in applications requiring high efficiency and accuracy. The resistor can be used in high frequency amplifier circuits, high current circuits, and digital devices. The resistance value of the L25J3R0E is determined by the number of terminals and is typically marked with the value on its surface. The three terminals are connected to the load path and the resistance value remains constant regardless of changes in the temperature or the current flow. The maximum power rating is 10 watts and the resistance range is from 0.5Ω to 9.9Ω. The working principle of L25J3R0E chassis mounted resistors is based on Joule’s Law which states that the power dissipated in a conductor is equal to the square of the current flowing through it multiplied by the resistance. This means that the L25J3R0E can dissipate a large amount of power over a wide range of currents. The L25J3R0E chassis mounted resistor is constructed using 28 strips of resistor materials bonded directly to the insulating substrate. This design provides a low thermal stability and a high current capacity. The thermo-compensation element ensures low noise performance and low drift coefficients, giving the resistor a high level of accuracy.One of the main advantages of the L25J3R0E is its high reliability, which is due to its low thermal stability and high current capacity. It has a wide operating temperature range between -55°C to +125°C and is resistant to ambient temperature changes and mechanical shock. It meets the requirements of MIL-STD-202G and is suitable for both fixed and power applications.The L25J3R0E chassis mounted resistor is suitable for applications that require voltage regulation, signal conditioning, and temperature compensation. It is commonly used in power supplies, amplifiers, digital devices, motor control systems, and other high frequency applications. In summary, the L25J3R0E is a three-terminal chassis-mounted resistor with a low thermal stability, low noise and high current capacity. It is suitable for applications that require high efficiency and accuracy, such as voltage regulation, signal conditioning, and temperature compensation. It has a wide operating temperature range and is resistant to ambient temperature changes and mechanical shock. The resistor is reliable and suitable for both fixed and power applications.
