Through Hole Resistors are one of the most commonly used type of resistors and can be found in many electronic circuits. They consist of a small cylinder of metal, usually copper or other metal, placed inside of a larger metal cylinder that is insulated from the smaller metal cylinder. This combination of cylinders has two terminals, one on the inside of the cylinder and one on the outside. The terminals are connected to a centre wire which is placed inside the resistance material.

Addressing the particular model, SQZ20AJB-18K, it is primarily a through hole resistor manufactured by Suntan, a professional manufacturer in the field of resistors. It is a 4.7 K Ohm 12-pin thick film resistor, consisting of four ceramic-insulated metal-film resistors mounted on a ceramic substrate. The resistor is widely used in applications such as power supply, temperature control circuit, and audio circuits.

The operating principle is simple. When a current is passed through the resistor, the metal film inside the resistor will resist or oppose the flow of electric current. This is why it\'s called a resistor. This resistance to current flow produces a corresponding voltage drop across the resistor terminals, and this voltage drop is then measured to determine the amount of current flowing through the resistor. This resistance is measured in Ohms, which is a unit of electrical resistance.

The SQZ20AJB-18K is a very popular through hole resistor and is a reliable choice for many electronic designs. This resistor is designed for high-temperature operation, meaning it can be used in applications where temperatures can exceed 150°C. Additionally, its thick film construction, along with its tight tolerance range and low noise characteristics, makes it suitable for applications where accurate signal and power supply is required.

In terms of design, the SQZ20AJB-18K is a 12-pin, 0.6mm pitch, thick film resistor, with a 4.7 K Ohm resistance value. This resistor is designed to be mounted on a printed circuit board and has a power rating of 0.4W, meaning it can handle up to 0.4W of power without any damage. It also has a wide operating temperature range of -55°C to +150°C, which allows it to be used in a wide variety of applications.

Overall, SQZ20AJB-18K is a reliable, high-performance through hole resistor suitable for many different types of electronic circuits. Its high temperature, tight tolerance range, and low noise characteristics make it suitable for high reliability electronic designs. Additionally, this resistor\'s robust design makes it ideal for use in high-power and high-reliability applications, such as power supply, temperature control circuit, and audio circuits.
