Through hole resistors are common components found in most electronic circuits. The CFR3WSJT-73-120K is a typical through hole resistor. It is an axial fixed resistor with a cylindrical shape, two metal wires welded to stoves at its opposite ends, and a layer of heat resistant insulation on its body. By connecting it to a circuit, the resistance of the resistor can be adjusted according to the alternating current passing through it. The CFR3WSJT-73-120K can be used for a variety of applications, such as current limiting, voltage regulation, current balancing, personal hearing protection, and heat acceleration.

The working principle of the CFR3WSJT-73-120K is relatively simple. It consists of two metal leads and a body inside. The body is made up of an insulator material, such as ceramic or plastic, which is filled with a varying amount of metal resistive material. When current passes through the CFR3WSJT-73-120K, the resistive material in the body converts some of the energy from the electric current into heat. The amount of energy converted into heat is correlated to the resistance of the resistor. The higher the resistance, the more energy is converted into heat, and vice versa. In other words, when an electric current passes through the CFR3WSJT-73-120K, its resistance is temporarily increased.

The CFR3WSJT-73-120K is also equipped with thermal-cycling protection, which helps to protect the resistor from overheating and damage. This thermal-cycling protection works by continuously monitoring the temperature of the resistor and reducing its resistance when the temperature reaches a certain point. This reduces the amount of energy that is converted into heat and helps to protect the resistor.

Aside from being used in electronics, through hole resistors such as the CFR3WSJT-73-120K are also used for safety purposes, such as limiting power on motors, preventing overload of electrical devices, and controlling the voltage and current of electrical circuits. They are also used in audio systems to control the volume levels of speakers and headphones. On top of that, through hole resistors can also be used to measure voltage, current, and resistance in various electrical circuits.

The CFR3WSJT-73-120K is a powerful and versatile component, and can be used in a variety of applications. Whether it is used for safety, control, or measurement, it plays an important role in the functioning of many different types of electrical circuits.
