Through hole resistors are a type of resistors that are designed for through hole mounting on a circuit board. The SQM700JB-13K is one type of through hole resistors, which has the features of fast response time, low leakage current, and high peak current capability. It is mainly used in automotive, consumer electronics, and industrial applications.

The SQM700JB-13K is a precision resistor with a wide range of on-board solutions for a variety of applications. It consists of two components: a thermistor and a resistive element. The thermistor acts as a temperature regulating component which will increase or decrease its resistance with the temperature. The resistive element will vary its resistance depending on the surrounding electrical field. The combination of these two components gives the SQM700JB-13K a wide range of functionality.

The SQM700JB-13K has a range of operating temperatures, with a minimum of -40ºC to a maximum of +125ºC. It is available in various sizes and shapes, with values ranging from 0.01Ω to 300KΩ. This range allows the use of the SQM700JB-13K in a wide variety of applications such as protection circuits, temperature sensing, current control and voltage regulation. The resistance also does not change drastically when exposed to air or vibration, which makes it an ideal choice for many industrial applications.

The working principle of the SQM700JB-13K is simple. The thermistor measures ambient temperatures, while the resistive element varies its resistance according to external electrical fields. When the thermistor senses a change in temperature, it will adjust its resistance to maintain a constant voltage across its leads. If the external field causes the resistive element to increase its resistance, the voltage across the device will also increase. Conversely, when the external field causes the resistive element to decrease its resistance, the voltage across the device will also decrease.

The SQM700JB-13K can be used in a variety of automotive, consumer electronics, and industrial applications. In automotive applications, it can be used in protection circuits for ECUs and EMCs, as well as current sensing and voltage regulation in alternators and starter motors. In consumer electronics, it can be used as temperature sensing elements, or to control the voltage and current in audio amplifiers and speakers. Finally, in industrial applications, it can be used as a current regulator in motor drives, and for voltage and current sensing in robotics and manufacturing systems.

In conclusion, the SQM700JB-13K is a precision resistor designed for through hole mounting on a circuit board. It consists of two components, a thermistor and a resistive element, which are combined to achieve a wide range of functionality. It has a range of operating temperatures with a wide range of resistance values, making it suitable for a variety of applications. The SQM700JB-13K has a simple working principle, where the resistance of the device changes depending on the temperature and external fields. Its wide range of applications from automotive to industrial further make it a versatile and useful device for modern day engineering.
