Through hole resistors play a critical role in electrical and electronic circuits as they are responsible for delaying, buffering, and limiting current. The SQM300JB-13R is a variable resistance thru-hole component that can be used in a variety of applications. In this article, we will explain the purpose of this type of resistor, its various applications, and its working principle.

Thru-hole resistors, also known as through-hole or axial resistors, are components with a wire lead that extends through the body of the resistor. Unlike surface-mount resistors, these components are designed to pass current through its lead wire, and they are typically used in power supply designs and various circuit protection applications. The SQM300JB-13R is a high-power, nonlinear, variable resistance thru-hole component with a power dissipation of up to 4 watts and a maximum operating temperature of +95°C.

The SQM300JB-13R can be used in a variety of application fields, including power control applications, voltage regulation, switching circuits, servo motors, and audio processors. Additionally, it can be used in automotive electronics, robotics, and other power systems. Its wide resistance range, high current rating, and nonlinear resistive properties make it a great choice for these types of applications.

The SQM300JB-13R works on a principle of resistive contact. This method involves the use of two resistive contact points, which are making and breaking contacts in succession. This causes the resistance of the component to vary in a nonlinear fashion. This is different from linear resistors, which have constant resistance values throughout their entire operating range.

In addition to its power control applications, the SQM300JB-13R can also be used for reliable current limiting and surge protection systems. When connected to a power supply, it can be used to limit the maximum current that is allowed to flow through the circuit, providing reliable protection against electrical surges. In audio applications, the SQM300JB-13R is often used to provide phase control and smooth frequency response, making it ideal for use in audio processors.

The SQM300JB-13R is a versatile, through-hole component that can be used in a variety of different application fields. Its high power and nonlinear resistive properties make it suitable for use in power control applications, voltage regulation, switching circuits, servo motors, and audio processors. Additionally, its reliable current limiting and surge protection features can provide reliable protection against electrical surges. Finally, its principle of resistive contact allows it to vary its resistance in a nonlinear fashion, making it suitable for use in audio applications.
