Benefits of Making Use of Resistor Networks to Design Electrical Circuits

When a set of individual resistors are arranged in such a way that they can function as a single component, such as arrangement is referred to as a resistor network. The arrangement can then act as a replacement of the discrete resistors in the circuit. This arrangement is made while considering the total resistance value that should be to be supplied to the circuit. The ideal resistor material for making resistor networks 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. The following are some of the benefits associated with resistor networks in circuit design.

There are numerous different applications for resistor networks. Resistor networks find a wide range of applications across the electronics industry. This is because they have superior qualities to the individual discrete resistors. Commercial and military, as well as medical and industrial devices mainly make use of resistors in network. They are also used in transistors, sensors and many other devices that require resistors. Because of the unique characteristics of each device, it’s necessary to design the resistors in way that addresses these needs. 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. When thick film resistors are arranged into a network, they are constructed in single in-line modules vertically. 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. You can also adopt a high packing density of tracks and gaps because of the less space required for mounting.

Heat dissipation from the circuit is improved when resistor networks are used. One of the greatest functions of a resistor network in a circuit is to get rid of the accumulated heat. Thus, it is necessary to adopt an arrangement of the board that will ensure there is maximum dissipation of heat. The arrangement that makes this possible is the network resistor design. This can be explained by the fact such resistors are mounted vertically on the board to facilitate ease of air flow.

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. And it is this similarity in properties such as size of individual resistors that makes value matching possible for the resistor networks.
