Through hole resistors are one of the most common components used in designing electrical circuits. Even though surface-mount resistors have made significant advances, through-hole resistors are still widely used in a variety of applications. This article will discuss the application field and working principle of the 20J39RE through-hole resistor.
Application Field of 20J39RE
The 20J39RE through-hole resistor is a popular choice for many applications. It is used in audio circuits and amplifiers, as well as power supplies, computers, and embedded systems. This resistor is also found in automotive, RF, and telecommunications circuits. Its primary purpose is to limit the current in a circuit by providing a precise resistance value.
Working Principle of 20J39RE
The 20J39RE through-hole resistor is based on a carbon-film technology. A carbon-film resistor consists of a-wound resistor element covered with a thin film of carbon and then coated with an insulating material. The winding of the element is usually made of manganin, which is a low resistance alloy that can withstand high temperatures. The element is then terminated at both ends with flat metal end caps, which are connected to the two legs of the resistor. The resistance value is determined by the length of the element and the thickness of the carbon film on it.
When current is applied to the 20J39RE through-hole resistor, it will create a voltage drop across its terminals. This voltage drop is proportional to the applied current, and it is also affected by the resistance value of the component. The amount of resistance is also determined by the temperature of the environment, so heating or cooling the component can affect its resistance value. Additionally, the resistor also has a power rating, which indicates the maximum amount of power that it can dissipate safely.
Conclusion
The 20J39RE through-hole resistor is a versatile and reliable component that can be used in many different applications. It is based on the carbon-film technology and its resistance value is determined by the length of its element and the thickness of the carbon film on it. Additionally, its power rating indicates the maximum reliable power it can dissipate safely. This resistor can be used in a variety of circuits including audio, automotive, RF, and telecommunications.
