Through Hole Resistors (THRs) have existed for centuries and are an essential part of many electrical and electronic circuits. They are used to regulate or reduce the flow of electrical current or to act as a buffer between the components of a system. While a wide range of resistors exist, one particularly versatile option is the SQMW210RJ. This resistor is widely used and in the following sections, we will elucidate its application field and working principle.

Application Field

The SQWM210RJ through hole resistor is a four-terminal, wire-wound unit designed to operate in high current environments. It is widely used in power automation systems, instrumentation, motor drives, and industrial control systems. It is also employed in demanding situations where ruggedness and reliability are critical, such as on-board electronics, space vehicles, and aircraft.

Additionally, its superior thermal design capabilities and minimal loss characteristics make it suitable for use in power rectification, inductor, and commutator applications, and more. SQMW210RJ is able to withstand voltage overloads due to its thick insulation and can operate in temperatures between ambient and +300°C (+572°F).

Working Principle

The SQMW210RJ utilizes a four-terminal, wire-wound construction that provides superior current control capabilities. Its metal-clad construction enables it to handle high-currents and temperatures, as well as withstand voltage overloads. It is designed to operate in a linear fashion by sliding between 0%-100%, meaning that as the voltage across the unit increases, the current conduction increases linearly.

In addition, the SQMW210RJ employs a wide range of advanced technologies to monitor and control the operation of the resistor. These include temperature control, voltage control, and fault detection. The resistor is also equipped with a built-in short-circuit protection circuity to prevent it from overheating and suffering an electrical fault due to overvoltage forces.

The SQMW210RJ is also rated to a maximum power of 210W, making it ideal for applications that require higher wattage. To ensure optimal performance, the resistor is equipped with a monitoring port which can be used to detect and monitor overvoltage and overtemperature conditions, ensuring that the resistor maintains optimum performance at all times.

Conclusion

SQMW210RJ is a four-terminal wire-wound resistor designed for use in high-current applications, such as power automation systems, instrumentation, motor drives, and industrial control systems. Its superior thermal design capabilities and minimal loss characteristics makes it suitable for use in a wide array of applications. In addition, its monitoring port can be used to detect and monitored overvoltage and overtemperature conditions, ensuring that the resistor maintains optimum performance at all times.
