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. These networks are then taken to replace the single resistors in the circuit. The resistors are usually combined together within the device so as to provide the required resistance. The ideal resistor material for making resistor networks is the thick film technology. It is preferred because of its favorable characteristics that include good capacity to handle power, high resistance output per unit area as well as its lower cost when compared to other materials. Highlighted below are some of the benefits of incorporating resistor networks into circuit designs.
Resistor networks have a wide range of applications. Those who create electronic products make use of resistor networks in various ways. This is explained by the fact that the resistor networks have better performance characteristics than their single counterparts. Network resistors are used to designed devices for industrial and commercial use as well as medical and military applications. Some of the devices that use network type resistors are sensors and transistors. Different gadgets require that the network resistors be designed in different ways to mirror their unique properties. For instance, sensor resistors use value matching as an important property while those used in pull up/pull down applications do not need it.
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. Additionally, it is possible to greatly improve the packaging density of the board because the network system makes use of high density track and gap networks.
Resistor networks enhance the heat dissipation capacity of the circuit. One of the greatest functions of a resistor network in a circuit is to get rid of the accumulated heat. Their arrangement on the circuit board should therefore be in such a way that it’s possible to achieve the maximum possible heat dissipation from the circuit. 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. This is explained by the fact that value matching depends on a number of crucial factors like the change of load across the resistor, size of the resistors and also the temperature coefficient of resistance. Its crucial to ensure a similarity of properties for the individual resistors that make up the network. This proximity or similarity in size and other characteristics makes value matching easier in networks than in single resistors.
