Through Hole Resistors

The VM5JB2R70 is a through-hole resistor of the family of fixed resistors. This type of resistor is a two-terminal, non-inductive component. It is composed of a ceramic core, wrapped in an insulated coated wrap. It is the primary workhorse of electronic circuits due to its low cost, small size, and ability to provide precise resistances between two parts of a circuit. They are available in a variety of shapes and sizes, allowing for different types of applications.

Application Field

Through-hole resistors are most commonly found in applications where signal or power level control is needed.
For example, in audio-video equipment, many resistors are used to control volume and gain levels. These resistors can be of the through-hole version, or the surface-mount version for less visible applications.
Utilizing through-hole resistors allows for a high stability of the signal, while surface-mount types provide a shorter connection between components.
Due to their small size, these resistors are also very common in portable devices such as phones, tablets, and handheld consoles. The small size combined with the low cost makes them a very desirable choice for many applications.

Working Principle

The working principle of through-hole resistors is based on the fact that electrons moving through a conductor have to overcome a certain resistance.
As the electrons move through the resistor’s core, they come into contact with energy-dissipating layers of insulation. This energy loss creates a certain amount of heat which is then dissipated to the environment.
The resistance is determined by the number of layers of insulation, the material used, and the thickness of the insulation. The thicker the insulation, the higher the resistance.
By using different types of insulation, different types of resistors can be constructed to meet the electrical requirements of a circuit.

Conclusion

The VM5JB2R70 is an example of a through-hole resistor readily available on the market. It offers many advantages over other types of resistors, including low cost, small size, high stability, and the ability to provide precise resistances. Additionally, through-hole resistors can be used in applications where signal control or power level control is required, such as in audio-video equipment, portable devices, and handheld consoles. The working principle of these resistors is based on the fact that electrons moving through a conductor have to overcome a certain resistance created by energy-dissipating layers of insulation.
