Chassis Mount Resistors refer to those resistor devices that are specially built to be mounted to the faceplate of an enclosure or case. This style of mounting the resistors provides a more secure and reliable installation than just relying on wire leads. Such resistors are designed to have the body serve as a mechanical heatsink when in operation, dissipating the heat away from the resistor element. It\'s important to note that chassis mount resistors are often used in high wattage or high power applications, which makes them even better suited for a secure mount than other resistor types. In these cases, it is even more crucial that the resistor be securely placed to ensure safety and performance.The TJT30033RJ is a chassis mount resistor that operates using a J-style mounting system. This style uses two threaded fasteners for secure affixing to the faceplate, the body of the resistor providing the mechanical heatsink for the majority of the heat dissipation. It has a total resistance of 33 ohms, and a power rating of 3 watts. Its element is composed of a tubular luminous noninductive material, which in this case has a voltage polarization of less than +/-20%. This makes it appropriate for applications that require little voltage bias and are AC-line applications.In addition to the TJT30033RJ, there are many other types of chassis mount resistors with different specifications that allow for use in specific applications. For example, the RC-120CB is a 1/4 watt chassis mount resistor with a resistance of 560 ohms, and is particularly suited for use in audio-frequency applications. The DR-511 is another 1/4 watt chassis mount resistor, but it has a rating of 500 ohms, and is specifically tailored for use in low-frequency circuits.The main benefit of chassis mount resistors is their secure installation, as opposed to traditional through-hole resistors which are supported only by wire leads. This makes them a secure option for applications that require higher wattage, such as in motor drives, electrical power components, and other high-current devices. The chamber heatsink provided by the body of the resistor also provides a better alternative to other methods of dissipating heat, such as attaching extra heatsink elements. Additionally, chassis mount resistors have the ability to minimize vibration and shock, which also makes them a good choice for applications involving motors and other heavy equipment.The TJT30033RJ is a perfect example of a 3-watt chassis mount resistor. Its J-style current mount system makes it a secure choice for applications requiring considerable wattage, and its 33-ohm resistance value and voltage bias make it suitable for AC-line applications. With its secure installation and superbly dissipated heat, it is a perfect choice for those looking for a reliable solution for their application.
