Chassis Mount Resistors

Chassis mount resistors are components that are physically attached or mounted to the frame or chassis of an electrical enclosure. This type of resistor is primarily designed for absorbing energy or dissipating heat to prevent injury or damage to the electronic circuit.

Notable characteristics of chassis mount resistors are the ability to effectively dissipate heat, a relatively small size, and the capability to absorb high levels of power. These components are used across many industries, such as medical, automotive, and industrial electronics.

TJT3002R2J

The TJT3002R2J is an example of a chassis mount resistor. It is a high-power, standard-recovery, square-body T/R disc resistor soldered to a metal chassis.

Application Field of TJT3002R2J

The TJT3002R2J is primarily used in automotive, medical, and industrial applications that require effective energy absorption and Heat Dissipation (HD). The resistor is well-suited for applications that need a custom size, ruggedness and reliable performance. Some of the specific applications include:

• Lighting and lighting systems
• Heat sinks for thermal management of automotive engines and components
• Power supplies
• Power switching circuitry
• Battery chargers and converters
• Power line protection circuits
• Video-based security systems

Working Principle of TJT3002R2J

The TJT3002R2J works by absorbing excess energy and dissipating it to the chassis. When an excessive amount of energy passes through the resistor, it generates heat and is dissipated to the metal chassis. This heat along with the excess energy is then expelled from the system. The benefit of using this resistor is that it prevents the component from getting damaged due to too much heat, and it increases the overall efficiency of the system.

When using the TJT3002R2J, it is important to follow all the manufacturer’s instructions, so that the resistor is properly installed and correctly dissipates the generated heat. The resistor should be installed in a location that allows for proper air circulation and when possible, it should be placed away from potential sources of heat. This helps ensure optimum thermal management and reliable performance.

Conclusion

The TJT3002R2J is a highly efficient chassis mount resistor from the TJT family. This resistor is used in numerous applications that require effective energy absorption and heat dissipation. It offers excellent performance in space-constrained systems and the ability to withstand extreme temperatures. The resistor provides reliable operation and can be used to safely deflect excess energy from components to the chassis.
