Chassis Mount Resistors

Chassis mount resistors are components that are often used in circuits to limit the current flow and interrupt over-voltages. They are designed to be supported by the chassis and mounted to the board of a circuit. They are typically wide, cylindrical components that sit on holes on the board and securely connect to the chassis.

THS1512RJ is a chassis mount resistor with a resistance value of 12Ω. It is made of a special type of carbon film resistive material that provides excellent stability over temperature. It features a large diameter of 0.25 inches (6.35 mm) and is designed to dissipate heat quickly, ensuring the board runs at safe temperatures. It is suitable for a wide range of applications including industrial and automotive.

The working principle of THS1512RJ is fairly straightforward. The component is designed to allow electric current to pass through it and then create resistance in the circuit, which limits the current. Most resistors are designed to provide current limiting, but this one also has some additional features which make it better suited to demanding applications. Firstly, it is able to dissipate heat quickly, meaning it does not overheat and risk damaging components. Secondly, it is incredibly stable over temperature, resulting in precision current limiting performance. And finally, it has a large diameter which helps spread out the heat and ensure the board runs at safe temperatures.

In addition to its current limiting feature, THS1512RJ also provides protection from over-voltages. This is because its resistance increases at higher voltages, thus limiting the current flow and preventing damage to other components in the circuit. This is why it is particularly popular in industrial and automotive applications, as these often involve higher voltages which can be damaging to other components.

Overall, THS1512RJ is an excellent choice for current limiting and protection from over-voltages. Its wide diameter and excellent temperature stability make it perfect for demanding applications, while its ability to dissipate heat quickly ensures that it can be used in any board without putting other components at risk.
