Chassis Mount Resistors

The use of chassis mount resistors has found its way into many different industries, from consumer electronics to the automotive industry. These types of resistors are employed to regulate or control the flow of current in electrical applications and are different from wire-wound resistors, which are designed for more high current applications. The TE80B39RJ module is one such chassis-mount resistor module.

TE80B39RJ application field

The TE80B39RJ is a 2U19C-BA3 high-power, surface-mounted, two-layer resistive device, external connection resistor module. It is designed for applications requiring numerous quick-connect resistors that are few in size and easy to mount. This module is most commonly used in motor control, automotive electronics, power systems, and other applications where a large number of resistors is necessary. The TE80B39RJ has been designed to generate reliable, precise resistance of up to 1 ohm with an accuracy of +/- 0.05%.

TE80B39RJ working principle

The TE80B39RJ utilizes a patented radial connection technology to deliver adjustable resistance levels. The resistor is equipped with a four-pin connector that is used to connect it to the main circuit. This pin connector is made out of a reinforced steel housing and has silver-plated contacts, providing maximum electrical and thermal performance. The TE80B39RJ also features three control paths, which are the pins that control the nominal (fixed) resistance of the resistor, the coarse adjuster resistance, and the fine adjuster resistance. To adjust the resistance of the resistor, one of the paths is used to connect the resistors in series or parallel. For example, the nominal resistor can be connected in series to increase the resistance of the resistor, or connected in parallel to reduce the resistance. The coarse and fine adjusters are then used to fine-tune the resistance of the resistor. The coarse adjuster can be used to adjust the resistor over a range of approximately 100 ohms, while the fine adjuster can be used to adjust the resistor in increments of 10 ohms.In addition, the TE80B39RJ module is also equipped with an onboard thermal protection system called the thermalcutoff. This protection system will automatically shut down the module if the internal temperature exceeds an acceptable limit. This further increases the safety and reliability of the module.

Conclusion

The TE80B39RJ is an ideal chassis-mount resistor module for applications requiring an adjustable resistance. Its four-pin connector, three control paths, and onboard thermalcutoff provide reliable, precise resistance levels that can be adjusted over a wide range. Whether in motor control, power electronics, or automotive electronics, the TE80B39RJ is an excellent choice when it comes to adjustable resistors.
