Through Hole Resistors (THR) are a type of electric resistor that is installed in a hole and secured in place with a solder. These resistors are very important components in electronic circuit design, as they provide an electrical isolation between different parts of the circuit. In this article, we will discuss the characteristics and working principles of the WW12FT137R THR resistor.
Overview
The WW12FT137R THR resistor is a 12k Ohm resistance element. It has a standard size of 1/4” and is composed of two pieces of insulated copper wire that has been twisted together and then attached to a ceramic substrate with solder. The resistor is also equipped with a sleeve to protect it from vibration and thermal stresses. It is available in two varieties, a surface-mount version and through-hole version that can be easily mounted on a printed circuit board (PCB).
Application Fields
The WW12FT137R THR resistor is typically used in a variety of industrial and consumer electronic applications, such as in power supplies, switch mode power supplies, motor drives, audio amplifiers, etc. The Through Hole version of the THR resistor is also often used in combination with other components to create a variety of different types of circuits, such as logic circuits, analogue circuits, and digital circuits. The THR resistor is also often used in safety circuits, where its high isolation property is advantageous.
Working Principle
The working principle behind the WW12FT137R THR resistor is quite simple. When current flows through the resistor, the electrical energy that it transmits is dissipated as heat. This heat is then dissipated to the environment. As the electrical energy is dissipated as heat, the voltage across the resistor is reduced, which in turn causes the current to decrease. The process is known as Ohm\'s Law, which states that voltage (V) is equal to the resistance (R) multiplied by the current (I). Therefore, the lower the resistance provided by the THR resistor, the lower the voltage, and the lower the current.
Conclusion
The WW12FT137R THR resistor is a very useful component in the design of a variety of electronic circuits. It is capable of providing electrical isolation between different parts of a circuit, which helps to ensure the safe operation of that circuit. Furthermore, its ability to dissipate electrical energy as heat also helps to protect the circuit from excessive power delivery. Finally, its small size and low cost makes it an ideal choice for many applications.
