Through Hole Resistors are a type of electrical resistor that is mounted to a printed circuit board by drilling a hole and then mounting the resistor in the hole using an appropriate technology. The SQM10SJB-100K is an example of this type of resistor and falls into the surface-mount category. This resistor is constructed with a resistor chip and a copper-clad PCB and has a high power rating of 100KW. Its temperature range is -55°C to +105°C.

The SQM10SJB-100K is typically used in the automotive and military industries as an overcurrent protection device. It is also used in AC & DC voltage regulation applications and in pulse-control and relay protection circuits. Its typical features include a high thermal conduction, low noise level, and low power consumption.

The working principle of the SQM10SJB-100K is based on the concept of a negative temperature coefficient (NTC). This means that when the temperature increases, the resistance of the resistor decreases (the NTC theorem). This property of the resistor makes it an ideal choice for overcurrent protection, as it will react to any increase in current with a decrease in resistance, thus preventing any further rise in temperature.

To ensure the required current is limited to the rated power of the resistor, this type of resistor features a protection circuit that monitors the current. When a pre-defined maximum current is reached, the protection circuit is activated, shutting off the power to the resistor. This feature reduces the risk of the resistor becoming overloaded or overheating. The rated power, in this case, is 100KW.

In addition, the SQM10SJB-100K is designed to offer a consistent response and good performance over its lifetime. It is able to tolerate high temperatures, humid environments, and corrosive substances, making it highly reliable and suitable for use in many different applications. The resistor is also relatively small, allowing it to be installed in space-limited areas with ease.

Due to its high power rating and versatile design, the SQM10SJB-100K is widely used in a variety of automotive, military, and industrial applications. It is commonly employed in electric vehicle systems, high-frequency inverters, energy storage systems, power converters, and AC & DC current regulation.

Overall, the SQM10SJB-100K is a highly reliable and robust surface-mount resistor, suitable for use in a multitude of applications. Its NTC nature, protection circuit, and excellent performance over its lifetime make it an ideal choice for overcurrent protection, AC and DC voltage regulation, and pulse-control and relay protection circuits. This resistor is designed to operate in a wide range of temperatures and environments, making it suitable for use in a variety of different industries.
