Chassis Mount Resistors

Chassis Mount Resistors are components that are mounted on the chassis or frame of an electrical device. It is often in the form of a cylindrical or rectangular bar with its two ends recessed into a chassis, allowing for a secure point of contact. Resistor is a passive electrical component that “resists” the passage of electrical current. It is commonly used to reduce or split up the current passing through the circuit, or to provide necessary and precise voltage levels at particular points of the circuit.

L50J7K5E is a well-known type of Chassis Mount Resistor, which is a high-precision resistor used in intelligent power module applications. It is a high-stability automotive grade power resistor in a 0.5W package, with a temperature coefficient of resistance (TCR) of 50 ppm/K, a resistance range of 0.2 Ohm ~ 1000 Ohm, a voltage of 350V, and a power rating of 0.5W.

Application Field

The L50J7K5E is specifically designed for use in automotive applications, such as power supplies. It is suitable for a wide range of power control tasks, including battery and DC motor control, current limiting and over-current protection. Additionally, it is suitable for a variety of other applications, including AC motor control, energy storage and switching as well as servo motor control.

Aside from applications in the automotive industry, the L50J7K5E is also suitable for use in a wide range of consumer electronics applications, such as TVs, air-conditioners, refrigerators, and washing machines. It is also suitable for use in industrial applications, including power plant control and automation systems, robotics, mechatronics and machine handover systems.

Working Principle

The working principle of the L50J7K5E is based on Ohm\'s Law, an important physical principle that states that the current passing through a circuit is proportional to the voltage applied to it, divided by the resistance of the circuit.

In a circuit with the L50J7K5E, it works to create a voltage drop, or divide up the current according to its resistance. When a voltage is applied across the component, it produces a safe, precise voltage level at the output. This allows the system to precisely regulate the power to individual components and regulate the temperature of the system.

The stability of the L50J7K5E is maintained by the precise resistor construction and the heat-dispersing fastening structure. Since the chassis mount resistor is physically secured to the frame, it is able to disperse any excess heat more efficiently. This helps to reduce the temperature of the system and improve the thermal performance and efficiency.

Conclusion

The L50J7K5E is a high-precision Chassis Mount Resistor designed for power control applications in the automotive and other industries. It is based on the simple yet effective principle of Ohm\'s Law, and is constructed to meet a wide range of voltage, current, and temperature requirements. Its chassis mount design helps to improve the thermal performance of the device, and its ability to disperse heat efficiently helps to enhance its stability.
