Through Hole Resistors

A through hole resistor is a type of resistor used in electronic circuits for controlling electrical signal levels. Through hole resistors are one of the most common types of resistors and can be used for a variety of applications. This article will discuss the application field and working principle of a through hole resistor known as the CW01020R00KE12.

Basic Structure

The through hole resistor is constructed of an insulating substrate material. A lead (sometimes called a tie) is a metallic conductor that passes through a hole in the substrate. The substrate provides electrical insulation between the leads. The leads are usually connected to two contact surfaces, which are typically a metal plate or a wire.

Working Principle

A resistor works on the principle of Ohm’s Law which states that current is proportional to the voltage across the resistor. Thus, if the same amount of voltage is applied across two different resistors, the one with the lowest resistance will allow more current to pass through it than the one with the higher resistance. As the current flows through the resistor, some energy is dissipated as heat due to the resistance. This is why resistors are sometimes referred to as “heaters”.

Application Field

Through hole resistors is widely used in consumer electronics such as mobile phones, tablets, laptops, and other personal computers. They are also used in the automotive industry, robotics, appliances, instrumentation, and medical equipment. Through hole resistors are often used in power supplies, circuit protection, signal isolation, noise suppression, and motor control. Because of their low cost and high reliability, through hole resistors are commonly used in signal conditioning applications.

CW01020R00KE12

The CW01020R00KE12 is a through hole resistor commonly used in medium power applications. It has a standard operating temperature range of -55°C to +125°C. It is made from flame retardant, high temperature plastic material and features gold plated solderable pins. The CW01020R00KE12 has a maximum power dissipation of 4.5W, a Tolerance of ±5%, and a low resistance value of 1.02Ω.

Advantages

One of the main advantages of through hole resistors is their low cost and high reliability when compared to other types of resistors. They are widely available, and can be easily replaced when needed. Through hole resistors are also less susceptible to vibration and shock, making them great for applications that require durability. Finally, through hole resistors are easy to solder, making them ideal for quick and easy installations.

Disadvantages

The main disadvantage of through hole resistors is their limited power handling capability. Since they are in direct contact with the substrate material, they tend to overheat if the operating temperature exceeds their rated value. In addition, through hole resistors can take up more space on the board when compared to other types of resistors.

Conclusion

The CW01020R00KE12 is a through hole resistor commonly used in medium power applications. It has a standard operating temperature range of -55°C to +125°C, a maximum power dissipation of 4.5W, a Tolerance of ±5%, and a low resistance value of 1.02Ω. Through hole resistors are one of the most common types of resistors and can be used in a variety of applications due to their low cost and high reliability.
