Through Hole Resistors, such as the SQM700JB-4R3, are electronic components that generate a specific electrical resistance value when current passes through them. This resistance value can be used to regulate the current that is passing through the device, provided that the correct level of resistance is used when installing the resistor.

The SQM700JB-4R3 is a through hole resistor used in a wide variety of applications. It is a standard 4.3Ω resistor that is designed with a TO-220 package. This type of resistor is often used in applications where a higher power dissipation and voltage is needed. It is also often used for signal and power applications as it is designed to dissipate heat efficiently, making it suitable for high-frequency applications.

In addition, the SQM700JB-4R3 is designed with an angled lead design that allows for quick and easy mounting on PC boards. This makes it an ideal choice for applications that require a low mounting profile or where there is limited space available for mounting the resistor. As such, it is often used in radio frequency (RF) applications, as well as automotive electrical systems and industrial motors.

The working principle of the SQM700JB-4R3 is relatively simple. When current passes through the resistor, a voltage is generated across the resistor, causing a current to flow. The resistor then acts as a dissipator, converting the electrical energy into thermal energy, which is released as heat. This results in a decrease in the voltage across the resistor, which in turn regulates the current flowing through the resistor.

The SQM700JB-4R3 can be used in a variety of applications where high power and voltage dissipation is required. It is commonly found in RF applications, automotive systems, and industrial motors. In addition, its angled lead design makes it an ideal choice for applications that require a low mounting profile or limited space for mounting the resistor. As such, the SQM700JB-4R3 is a versatile and reliable resistor choice for a variety of projects.
