Through Hole ResistorsThrough hole resistors are a type of resistor that is fixed in place using a simple, yet efficient technique. This technique is accomplished by drilling a hole through the PCB, mounting the resistor to it, and soldering the leads onto both sides of the board. These resistors are designed to have a relatively high resistance and usually have a large thermal coefficient, meaning they are very heat sensitive and their resistance might change drastically according to the environment.The most commonly used through hole resistor is the MK18R2FE-R52. This resistor is made up of a ceramic core, an external crimped metal shell, and two terminals. The metal shell provides the resistor with a high level of protection from dust, moisture, and other environmental hazards. The two terminals are usually stamped in place with a crimping tool in order to provide a secure connection to the PCB. The ceramic core is designed to have a low Effective Thermal Conductivity, meaning it is able to dissipate the heat evenly, ensuring a consistent resistance.The MK18R2FE-R52 is primarily used in consumer electronics for Automotive DC applications, Motor control, and Data Controllers. In Automotive DC applications, the MK18R2FE-R52 is used to manage the current flow in various circuits, including charging ports, panel lights, and indicator lights. In Motor Control, the MK18R2FE-R52 is used to control the speed of the motor and ensure that it operates smoothly. Finally, in Data Controllers, the MK18R2FE-R52 is used to regulate the flow of signals between devices in order to ensure the accuracy and reliability of the signal.This resistor is especially suited for Automotive DC applications because it is able to withstand higher temperatures, up to 175°C. It is also able to tolerate more voltage than most other resistors, making it ideal for handling the higher voltage of automobile circuits. Furthermore, it has a low Effective Thermal Conductivity, meaning that it is able to dissipate the heat created by high current applications and maintain its resistance even under harsh conditions.The working principle of the MK18R2FE-R52 is relatively simple. When the current passes through the resistor, it is met with resistance and this friction is converted to heat. The heat is dissipated by the ceramic core which ensures that the resistor maintains its resistance and does not overheat.In conclusion, the MK18R2FE-R52 is an ideal resistor for Automotive DC applications, Motor control, and Data Controllers due to its high voltage tolerance, high temperature tolerance, and low Effective Thermal Conductivity. This resistor is simple yet efficient, making it a great choice for any project.
