Benefits of Making Use of Resistor Networks to Design Electrical Circuits
Resistor networks area usually an arrangement of several resistors into a single component that can function as a unit. The arrangement can then act as a replacement of the discrete resistors in the circuit. The resistors are usually combined together within the device so as to provide the required resistance. The most common design material used in this case is the thick film technology. The reason why it is favored is because it has better qualities that include its high resistance measured per unit area, high power handling capacity as well as low cots when likened to other materials. Here are some of the advantages of using resistor networks in circuit design.
There are numerous different applications for resistor networks. The electronics industry requires resistor network for many different applications. This is explained by the fact that the resistor networks have better performance characteristics than their single counterparts. Commercial and military, as well as medical and industrial devices mainly make use of resistors in network. They are incorporated into sensors, transistors, and various other devices. The way the networks are designed for each application is different, depending on the unique features of the device. A good example is the resistor networks for sensor which require value matching as an important consideration while others do not.
Use of resistor networks creates the possibility of saving circuit board space. It is possible to adopt a single line module arrangement of resistor networks which can be mounted vertically. The arrangement takes up less space on the circuit board when compared to mounting of discrete resistors on the board. Greater density of packing and mounting the resistors can therefore be used due to limited
space taken up on the board.
Resistor networks enhance the heat dissipation capacity of the circuit. Heat dissipation is a major function of the resistors in an electrical circuit. Thus, it is necessary to adopt an arrangement of the board that will ensure there is maximum dissipation of heat. The resistor network arrangement is the most ideal arrangement to achieve the maximum heat dissipation possible. This is because they are normally mounted vertically on the board, allowing the air to flow more freely as compared to the discrete resistors.
Value matching is possible. Value matching is a function of numerous factors such as the coefficient of temperature resistance, size of the resistors as well as the fluctuations of the load across the resistor. A resistor network is normally made up of resistors that have almost similar properties, if they are not all similar. And it is this similarity in properties such as size of individual resistors that makes value matching possible for the resistor networks.
