Through Hole Resistors And The H475RBDA Application Field & Working Principle

Through hole resistors, sometimes referred to as through hole technology, is a method for mounting components to a printed circuit board (PCB) using holes drilled into the PCB, with the components then inserted into the hole. This is the traditional technique for mounting electronic components and is used in a variety of applications. This technology has stood the test of time and remains the preferred method for many PCB designers and developers.The H475RBDA resistor is a through hole resistor with a power rating of 0.25W. It is designed to provide a very high resistance with very low capacitance. The applications of the H475RBDA include its use in medical, industrial, and consumer products where it is necessary to have a resistor with high resistance and low capacitance. H475RBDA resistors are also used in a variety of automotive, aerospace, and military applications.The working principle of the H475RBDA through hole resistor is based on its construction. The resistor is composed of a metal film deposited on an insulating substrate. The metal film is printed on top of the substrate and then the substrate is cut into a “doughnut” shape by etching. This effectively creates a cylindrical coil with a small gap between the top and bottom layers of the resistor. The resistor’s resistance is determined by the resistance of the deposited metal film itself as well as by the resistance of the insulating substrate. The deposited metal film typically consists of a combination of metal, such as molybdenum and copper. This combination of metals controls the current flow of the resistor.When the resistor is in use, it is powered by a DC voltage. The current flow is then regulated by the resistor’s resistance. It is also important to note that the H475RBDA through hole resistor has an exceptionally low capacitance of 0.25 picofarads, which means that it is suitable for a variety of high speed applications.The H475RBDA through hole resistor is an excellent choice for many applications due to its high resistance and low capacitance. It is used in a wide range of applications, including medical, industrial, and consumer products, as well as automotive, aerospace, and military applications. Its construction and working principle are based on its power rating of 0.25 W and its low capacitance of 0.25 picofarads. The H475RBDA through hole resistor is an important component in a variety of electronic systems and is an essential part of the design and development of any PCB.
