Through Hole Resistors (THR) are electromechanical components that are designed to resist the passage of current through a conducting material. They are typically made from ceramic tubes, metal foil layers, and other materials that are resistant to electrical stress. THR resistors have two major application fields: in analog circuits, where they are used to create a constant radio frequency (RF) current; and in digital circuits, where they are used to reduce noise caused by electrical shorts or other current interfering phenomena. The SQM700JB-0R12 is a THR resistor that is specifically designed for digital applications. In this article, we will take a closer look at the working principles and applications for this type of resistor.

The Working Principle of SQM700JB-0R12

The SQM700JB-0R12 is a precision resistor designed for digital circuits. It consists of three layers of metal foil, which are then sealed in a ceramic tube. The resistor is designed to resist the passage of current in two directions – up and down the tube. This resistance is achieved by using a ‘zero resistance principle,’ which causes the electrons to move around the resistor at a constant speed, rather than passing through it. This principle allows more control of the current, resulting in greater noise reduction and accuracy. The SQM700JB-0R12 resistor has a very low cutoff frequency of 0.2GHz, making it suitable for digital circuits with high frequency signals. The resistor also features an ultra-wide temperature range of -40°C to +125°C, which makes it suitable for a range of operating environments, including low to moderate current levels. The unit is highly robust, with a wide range of eyelet crimp options available.

Applications of SQM700JB-0R12

The SQM700JB-0R12 THR resistor is primarily used in digital circuits. One of the most common applications is in the electronic test and measurement equipment industry, where the resistor is used to measure precise parameters such as current, voltage, and resistance. The resistor is also used in automotive electronics as an integration element in safety systems and diagnostic equipment. In addition, the SQM700JB-0R12 is also used in defence applications such as navigation systems and missiles. The SQM700JB-0R12 THR resistor is also used in communications systems, particularly those that require high-precision signal levels. It is suitable for low to moderate current levels and has a very low cutoff frequency, making it ideal for digital circuits. Moreover, the resistor is made from robust materials, such as metal foil and ceramic, making it suitable for a range of operating environments.

Conclusion

The SQM700JB-0R12 THR resistor is a highly robust and precise resistor designed for digital circuits. It is typically used in test and measurement equipment, automotive electronics, defence systems, and communications systems. The resistor features an ultra-wide temperature range of -40°C to +125°C, making it suitable for a number of operating environments. Furthermore, the resistor has a very low cutoff frequency of 0.2GHz, making it suitable for high frequency signals.
