CJT8047RJJ

Chassis Mount Resistors are commonly used in electronics assemblies as part of a variety of components, including voltage dividers, attenuators, filters, and signal generators. The CJT8047RJJ is a type of chassis mount resistor ideal for applications requiring low-noise performance and high-bandwidth control. This article will explain the application field and working principle of the CJT8047RJJ.

Application Field of CJT8047RJJ

The CJT8047RJJ is an ultralow-noise precision resistor used in a variety of applications. Its major application fields are high-frequency analog and digital circuits, digital signal processing equipment, instrumentation, and telecommunications. Because it features a shielded metal enclosure with an internal thermal management system, it is capable of operating in high-temperature environments without performance degradation. Additionally, the CJT8047RJJ is ideal for use in impedance matching applications where high-frequency signals must be reliably transmitted between components.

Working Principle

The CJT8047RJJ is composed of a resistive material insulated by an electrically conductive carbon film. The resistor is connected to two metal wires, which are then connected to electrical power sources. When a voltage is supplied to the resistor, a current will flow through the material. This current will cause the resistance value to increase due to the heating effect, also known as self-heating. To compensate for the increased resistance value, the CJT8047RJJ uses temperature compensation, where a temperature-sensing circuit monitors the temperature of the resistor and adjusts the current flowing through it accordingly.

Additionally, to reduce noise, the CJT8047RJJ features a shielded metal enclosure with an internal thermal management system. The enclosure helps reduce the effect of external noise, and the thermal management system ensures that the resistor does not become too hot or too cold, which can lead to performance degradation.

Conclusion

The CJT8047RJJ is a high-performance chassis mount resistor ideal for a variety of applications where low-noise performance and high-bandwidth control is required. Its application fields include high-frequency analog and digital circuits, digital signal processing equipment, instrumentation, and telecommunications. It is composed of a resistive material insulated by an electrically conductive carbon film, and features a shielded metal enclosure with an internal thermal management system. This ensures that the CJT8047RJJ can operate reliably in extreme temperatures without suffering any performance degradation.
