Advantages of Using Resistor Networks When Designing Circuits
A resistor network consists of a single component which has several resistors connected together. The arrangement can then act as a replacement of the discrete resistors in the circuit. They are combined with the objective of providing a resistance that is required for the entire circuit. Thick film technology is usually as a material preferred for constructing resistor networks. 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.
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. A good example is the resistor networks for sensor which require value matching as an important consideration while others do not.
They are capable of saving space on the circuit board. Vertical mounting of single line module networks of resistors is possible. This kind of design takes up considerably less space on the circuit board as compared to the single discrete resistors when mounted directly to 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.
There is improved efficiency of dissipating heat in 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 arrangement that makes this possible is the network resistor design. This is because they are normally mounted vertically on the board, allowing the air to flow more freely as compared to the discrete resistors.
It is possible to do value matching with a network of resistors. 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. A resistor network is normally made up of resistors that have almost similar properties, if they are not all similar. This proximity or similarity in size and other characteristics makes value matching easier in networks than in single resistors.
