Through Hole Resistors, or THRs, are electronic components that are used to provide electrical circuits with the required resistance. A THR consists of two main parts: an insulator shell, and a resistive element. The insulator shell is made from a non-conducting material, such as porcelain or plastic, and it houses the resistive element. The resistive element is made from a material that has a high electrical resistance, such as carbon or metal film. The combination of the insulator shell and the resistive element creates a resistor that is able to withstand the electrical current that flows through it. The SQM300JB-18K is an example of such a THR.

The SQM300JB-18K is a small, surface mount, epoxy-coated THR, specifically designed for use in circuit boards of various types. The resistive element is cut from a metal-oxide film, giving it a high resistance and a long life expectancy. The epoxy coating ensures that the resistor is securely mounted and protected against environmental damage. The resistor has a wide range of operating temperatures, ranging from -55°C to +125°C.

In terms of its application field, the SQM300JB-18K is suitable for use in a variety of applications, including but not limited to, audio equipment, measuring instruments, industrial automation equipment, and automotive electronics. Its small size allows it to be placed in compact spaces, making it suitable for applications where space is at a premium. In addition, its resistance characteristics allow it to be used in applications where accuracy and repeatability are essential, such as the automatic testing of electronic components.

The working principle of the SQM300JB-18K is fairly simple. When a voltage is applied across the two end contacts of the resistor, electrical current will flow through it and will be diminished by the resistance of the resistance element. As the electrical current passes through the resistor, a voltage drop will occur. This voltage drop is proportional to the amount of current that passes through the resistor.

The SQM300JB-18K is a great example of a THR that is well suited to a variety of applications. Its small size, resilience, and accuracy make it a great choice for a range of different applications. It is able to offer a high level of performance in a range of conditions and is a great choice for temperature-sensitive applications. This THR is a great choice for those looking to integrate a THR into their circuit boards.
