Through Hole Resistors

Through hole resistors, also known as leaded resistors, are electronic components used to provide resistance or impedance to a current in an electronic circuit. They help to reduce electrical voltage and current, control the power consumption, and protect components from damage caused by over-currents. Through hole resistors are mostly used in high-frequency circuit applications, and they are especially useful for fast speed communication in automotive, consumer electronics, and industrial interface designs. The SQM700JB-1K3 is a through hole resistor with a wide range of application fields and a specific working principle.

Application Fields of the SQM700JB-1K3

The SQM700JB-1K3 through hole resistor can be applied to resistive element in over-current circuit protections, filter circuits, and voltage controlling circuits, for instance. In over-current protection circuits, when the voltage of an electronic device exceeds the pre-set safety threshold, the resistive load is cut by the over-current protection circuit. The SQM700JB-1K3 resistor has a stable resistance value and high accuracy, so it can effectively cut the circuit when the electric current exceeds the safe threshold value and protect other parts from the high voltage.

Besides being used in over-current protection circuits, the SQM700JB-1K3 also has wide applications in filter circuits and voltage controlling circuits. In filter circuits, it can be used to reduce the interfering signal from outside, ensuring that the low frequency signal is not affected by high frequency signals. In voltage controlling circuits, it can reduce large changes in voltage due to deviations in external electric current. As a result, it can provide more stable electric current output, which is beneficial in high-speed communication.

Working Principle of the SQM700JB-1K3

The SQM700JB-1K3 through hole resistor utilizes a flat plane resistor technique to achieve a wide resistance range from 1k to 3k. It works by increasing the surface area of the resistor, which helps to achieve a larger resistance value. The larger surface area also helps to improve the accuracy of the resistance value. The presence of five small holes on the body surface of the resistor, known as vents, further allows the air inside the resistor to escape, improving the heat dissipation capability of the resistor. This improved heat dissipation helps regulate the temperature of the resistor, and thus, the resistance value remains constant even when the temperature rises.

The accuracy of the resistor is further ensured due to the presence of grooves on the outside layer of the resistor. These grooves help to improve the uniformity of the resistance value, and this prevents large deviations in resistance value even if there are small variations in the tolerance level. Due to all these features, the SQM700JB-1K3 is able to maintain a high accuracy, even when it is used in highly demanding applications like high-speed communication.

Overall, the SQM700JB-1K3 through hole resistor can be effectively used in over-current protection, filter circuits, and voltage controlling circuits, due to its design that allows for wide resistance value range and high accuracy. It uses a flat plane resistor technology to increase its surface area, and grooves on its outer layer further ensure uniformity in the resistance value even when the tolerance level changes. It also has good heat dissipation capability to regulate its temperature, making it suitable for highly demanding electronic applications.
