Through Hole Resistors are one of the most popular types of resistors in the electronics industry. As the name suggests, they are typically constructed with a rectangular hole that is drilled or punched into a board. The hole is then filled with a metal or a non-conductive material, such as a dielectric resin. The size and depth of the hole will depend on the desired resistance level. The resistance is also determined by the material used, as well as the size of the hole.

The 20J7K5 application field and working principle is used in many electrical and electronic applications. It is a surface-mounted resistor that is typically used to provide a low-impedance connection between two or more points on a PCB. It is very common in telecommunication equipment, automotive circuits, and audio equipment. The 20J7K5 is also relatively inexpensive, making it ideal for mass production.

The 20J7K5 working principle is based on the Ohm\'s law, which states that the current flow through a conductor is directly proportional to the voltage applied across it. When a specific voltage is applied across the resistor, a specific amount of current will flow through it. The resistance of the resistor is measured in ohms, and the 20J7K5 resistor usually has a resistance ranging from 4.7 Ohm to 22 Kilo-Ohm, which is relatively low.

The typical structure of the 20J7K5 includes a pair of contact pins, which are used to connect the resistor to the board. These pins allow the current to flow through the resistor and the metal housing simultaneously. The metal housing of the 20J7K5 is usually designed to dissipate the heat generated by the resistor, which keeps the resistor from becoming overheated. It also ensures a reliable connection between the resistor and the board.

The 20J7K5 is typically used in many applications that require precise and dependable voltage regulation. Some of these applications include power supplies, switch mode power supplies, power amplifiers, and audio attenuators. It is also commonly used in high-frequency communication systems and as a replacement for traditional wire-wound resistors in power electronic circuits.

In summary, the 20J7K5 application field and working principle is based on the fundamentals of Ohm\'s law. It is an affordable and reliable surface-mounted resistor that is used in a variety of electrical and electronic applications. Its metal housing helps to dissipate heat and maintain a reliable connection to the board. The 20J7K5 resistor is typically used for precision voltage regulation, power supplies, and audio attenuators.
