MFR100FRE52-1M91 Through Hole Resistors: Application Field and Working PrincipleThrough hole resistors are passive electrical components that are installed by being inserted through a hole in the PCB board and then soldered to it. These resistors come in various sizes, shapes, and structures, the most popular being the MFR100FRE52-1M91 type. This type of through hole resistor is designed in a cylindrical shape, with a NTC thermistor composition, and a resistance of 1MΩ at 25 °C. Its wider, relatively flat terminations are designed to minimize risk of thermal fatigue and they also allow for easy installation on many types of PCB boards.The MFR100FRE52-1M91 through hole resistor has a number of applications in both industrial and consumer settings. For instance, in industrial settings it can be used to regulate the voltage of motor control and power distribution circuits, to limit the overcurrent flow of a circuit, and for surge protection. In consumer applications, it is used to control the current in LED lights, to limit the peak voltage of incoming signals, and to regulate the current level of audio and video devices.This type of through hole resistor is also designed according to a specific working principle. It works by limiting the flow of electric current through a circuit by decreasing the voltage drop across the component. This is accomplished through a variety of methods. Firstly, its composition of NTC thermistor changes its resistance when exposed to heat. As the temperature rises, the thermistor resistance decreases, resulting in lower current flow. Secondly, the physical shape of the resistor also has an effect, with cylindrical designs forming parallel resistances, and axial designs minimizing voltage drops caused by voltage surges.In order to achieve the best level of performance and protection, it is essential that the MFR100FRE52-1M91 through hole resistor is installed correctly. This should be done by making sure that the two sides of the resistor are securely connected to the desired circuit, and that the connections do not become loose. Additionally, the solder joints should be inspected for any defects, and extra care should be taken to prevent the component from coming loose, or falling out of its hole.In summary, the MFR100FRE52-1M91 through hole resistor is an extremely popular type of component, due to its wide range of applications and ability to regulate current, voltage, and surges. Its structure, composed of a NTC thermistor, is designed to provide protection and increase its resistance when exposed to higher temperature levels. Care should be taken to install the resistor correctly and to keep solder joints safe from potential damage.
