SQM300JB-120R

Through Hole Resistors are resistors with terminals that are physically larger than conventional resistors, making them great components for electrical designs that need higher connectivity. Some of the popular types of Through Hole Resistors are cermet-type carbon fixed, film-type carbon fixed, metal film, wirewound, and surface mount Through Hole Resistors. The SQM300JB-120R is a Through Hole Resistors that offers excellent reliability and stability for medium power applications and is designed for both through-hole and surface mount technology.

The SQM300JB-120R has a maximum power rating of 300W, and the electrical properties of this Through Hole Resistors include a stability of 0.5%, T.C.R. of ≤100ppm/°C, resistance range of 0.5~470Kohm, and operating temperature range of -55~+ 155°C. It also has relatively low loss characteristics, high surge withstanding capabilities, and high reliability. This makes it suitable for a variety of applications such as electric power meters, avionics, instruments, and consumer applications.

The SQM300JB-120R works by allowing an electrical current to flow through a ceramic material, which is filled with a chosen resistance material, such as carbon, controlled by a voltage across it. To control the voltage across the resistor, there is a constant current source that is between the ceramic material and the positive terminal. As the voltage on the resistor increases, the current through it increases, increasing the resistance, and vice versa.This current flow results in a conversion of electrical energy into heat energy, as the electrons collide with the atoms in the resistor material. The resulting heat energy is then dissipated from the resistor by way of convection, radiation or conduction.The SQM300JB-120R is designed for use in medium power applications, and its high reliability and excellent stability make it a great choice for any type of Through Hole Resistors application. Its temperature range above and below operating temperature also makes this resistor ideal for high power applications that require reliability and stability in a wide range of conditions. Its relatively low loss characteristics and high surge withstanding capabilities also add to its reliability and add to its range of application uses. The SQM300JB-120R is a great addition to any Through Hole Resistors component.
