Chassis mount resistors allow devices to be installed on the chassis of an industrial or consumer product. The TJT25068RJ is a chassis mount resistor with a maximum power rating of 250W and a resistance range of 1Ω to 10kΩ. This resistor is available in either Through-Hole or Surface Mount configurations. It is UL and CSA listed and ROHS compliant.
The TJT25068RJ is suitable for a wide variety of applications, ranging from precision measurement and industrial control to consumer products and automotive applications. These resistors have a high voltage breakdown and high pulse surge capability, making them ideal for applications such as motor speed control and current monitoring. The resistor is also capable of handling current spikes and other extreme conditions without damage.
The TJT25068RJ has two main components; the resistive element and the terminal tab. The resistive element is a helical wire-wound element, consisting of a continuous filament wrapped around a ceramic or metal core. The wire is insulated from the core by a ceramic-filled, glass insulation layer. This design allows for increased power handling and resistance accuracy over a wide temperature range. The resistive element is encased in a ceramic or epoxy housing to provide additional protection.
The terminals on the resistor are connected to the resistive element via two rivets, allowing for a secure connection with minimal contact resistance. The top of the case is open to provide easy access to the terminals, which can be soldered directly to the device or connected via wires. A wide variety of terminals are available, including quick-connect and spade terminals.
When installed on the chassis, the TJT25068RJ behaves as a voltage divider. This type of resistor works by utilizing the resistance inherent when current passes through the resistive element. In this configuration, the voltage at the terminals decreases as current passes through the resistor, allowing for precise voltage regulation. This voltage regulation is important in a variety of applications, such as to control motor speed or regulate the voltage levels in a circuit.
The TJT25068RJ is capable of handling high-power applications without sacrificing performance. With a maximum power rating of 250W and a wide range of resistance values, this resistor is ideal for many industrial and consumer applications. This chassis mount resistor is UL and CSA listed and ROHS compliant, making it a safe and reliable choice for your next electronics project.
