Through Hole Resistors: ERG-2SJ331 Application Field and Working Principle

Through-hole resistors are widely used in many electronic applications to provide resistance or impedance for regulating current flow between two components. The ERG-2SJ331 is an advanced through-hole resistor device designed for applications in which both high power and high-temperature stability are desired. This article will discuss the application fields of ERG-2SJ331 and its working principle.

Application Field of ERG-2SJ331

ERG-2SJ331 is an ideal resistor for temperature sensing, current limiting, and other similar applications. These uses may include power supply circuits, automotive applications, power regulation, and DC-DC converters. Additionally, the through-hole resistor can be used in circuits that require very reliable and stable operation, such as medical devices and industrial equipment.ERG-2SJ331 through-hole resistors feature a construction based on a ceramic base for improved temperature stability. The resistors feature an exceptionally low temperature coefficient of resistance (TCR) of ± 15 ppm/°C, making them suitable for temperature sensitive applications. They also have an operating temperature range of -55℃ to +155℃.

Working Principle of ERG-2SJ331

ERG-2SJ331 is primarily composed of a ceramic material and a metal contact element that has been precisely formed and mounted on an insulating base. This construction allows the device to maintain its resistance value and temperature coefficient even through extreme temperature changes.The resistance value is determined by the thickness and width of the metal contact element. The thickness and width are adjusted to achieve the desired resistance. The metal contact element is soldered to an insulated substrate, which is then mounted to the ceramic base. This type of construction is designed to minimize thermal expansion and resist mechanical shock and vibration.The temperature coefficient of resistance is determined by the material of the ceramic base and the metal contact element. The ceramic material is selected for its low thermal expansion, while the metal contact element is chosen for its high thermal conductivity and resistance to oxidation. Together, these two components are designed to create a very stable resistor.

Conclusion

ERG-2SJ331 is an advanced through-hole resistor ideal for applications that require a high power and high-temperature stability. It is composed of a ceramic material and metal contact element, which is mounted on an insulated base to achieve the desired resistance. Additionally, ERG-2SJ331 has a low temperature coefficient of resistance and an operating temperature range of -55℃ to +155℃, making it suitable for temperature sensitive applications.
