It features a wide resistance range from the standard 1.0 Ohm to 470.0 K Ohms. It provides excellent temperature stability and its resistance value remains low in temperatures ranging from -55°C to +150°C. The SQP700JB-11K has a power rating of 1/8 W and its dissipation ratio is 2.0, indicating that it can take up more energy than lower dissipation ratioed resistors. Its maximum temperature coefficient is typically ± 500 ppm/℃.

Application Field

Given its wide resistance range and reliable performance, the SQP700JB-11K is a popular resistor used in many applications. It is commonly used in base stations, communication systems, industrial control systems, measuring systems, drive systems, and more. In base station applications, the SQP700JB-11K is used in the power supply unit to provide an additional layer of protection when used with other high-performance components. It is also used in the RF signal amplifier circuit of microwave communication systems for connecting and bypassing feed and amplifier circuits, helping to reduce the noise generated by strong signals. In industrial control systems, it is used in control and signaling systems as well as in adjustable power supplies. For measuring systems, it is used to adjust the signal level and improve the resolution of signals in measurement circuits. Besides these applications, the SQP700JB-11K is also used in drive systems, such as for controlling speed and torque in stepper motor drives.

Working Principle

The working principle of SQP700JB-11K is simple and straightforward. It works the same as other fixed resistors. It has two terminals (or pins) that connect to the source and load. When a voltage is applied between these two terminals, an electric current will flow, which is determined by the resistance value of the resistor. The resistor reduces the voltage and current of the circuit, resulting in a lower power output. Thus, the resistor helps to protect other components in the circuit. On the other hand, it does not consume power, only dissipates it as heat.

The resistance value of SQP700JB-11K is fixed and does not depend on the current applied. It is very stable and reliable, making it suitable for many applications, especially ones that require a precise control of the flow of the current. Additionally, the SQP700JB-11K has a temperature coefficient of usually ± 500 ppm/℃, meaning that the resistance value does not significantly change with temperatures.

Conclusion

In conclusion, the SQP700JB-11K through hole resistor is a popular and reliable component with a wide range of applications. It is commonly used in base station, communication system, industrial control system, measuring system, drive system and more. Its resistance is stable and reliable in a wide temperature range. Moreover, its resistance do not depend on the current applied and its temperature coefficient does not change significantly. All these features make the SQP700JB-11K a popular choice in many applications.
