Through Hole Resistors

Through hole resistor (THR) refers to an electronic component in which a resistor is inserted into a through hole, and is mainly fixed by soldering or other methods. It is a mechanical component which is often used as a resistor in most of the electronic circuits. It is usually needed in the formation of circuits to reduce the current flow in one part of the circuit and therefore it is also used in various applications such as analog, digital and mixed-signal circuit designs.The RWR71S40R2FSB12 belongs to the THR family and its application field covers all kinds of general-purpose electronic circuits; in particular, this type of resistor is mainly used in the analog world, such as audio and video signals, voltage clamping, filter, power protection, pulse amplification, etc..The working principle of THR in general is very simple. The working principle of RWR71S40R2FSB12 THR is basically the same. Basically, parallel plates form an aquarium connected in series. A resistive element is arranged in series between the two plates. When an alternating current passes through the resistor, a magnetic field is generated in the vicinity of the resistive element. The magnetic field generated inside the resistor passes through the two plates with the current, and is then converted into heat in the resistor.The resistance of THR can be determined by the material, size, shape, and size of the resistive element, and the bypass wire used to reduce interference. The accuracy of the resistance value is also related to the parameters of the resistive element. The current method of measuring THR resistance is to measure the voltage drop across the resistor when a current is passed through it.In addition to the resistance of THR, its other electrical characteristics also need to be considered, including its resistance stability, temperature coefficient, voltage coefficient, and power coefficient. The RWR71S40R2FSB12 THR is able to meet all of these requirements.In conclusion, THR is a widely used component in electronic applications. The RWR71S40R2FSB12 THR is a reliable THR with excellent performance in the analog applications. Its working principle is mainly to convert current into heat, and its resistance value is also determined by the material, size, shape, and size of the resistive element. In addition, RWR71S40R2FSB12 THR also possesses excellent electrical characteristics, and is able to meet all of the requirements for accuracy and stability. With its reliable performance, the RWR71S40R2FSB12 THR is an ideal choice for those who are looking for quality THR in their electronic applications.
