Benefits of Making Use of Resistor Networks to Design Electrical Circuits

A resistor network consists of a single component which has several resistors connected together. These networks are then taken to replace the single 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. Thick film material is used because of its superior characteristics that include better power handling capacity, high resistance values per unit area and also lower cost in comparison with other materials. Here are some of the advantages of using resistor networks in circuit design.

Resistor networks have a wide range of applications. Resistor networks find a wide range of applications across the electronics industry. The network resistors usually have better qualities than the single discrete resistors. Network resistors are used to designed devices for industrial and commercial use as well as medical and military applications. 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. Resistors used in sensors, for instance, make use of value matching, which is not so much important for the pull up/pull down applications.
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. 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. Greater density of packing and mounting the resistors can therefore be used due to limited
space taken up on the board.

There is improved efficiency of dissipating heat in the circuit. One of the major functions of resistors in the circuit is to dissipate 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. With resistors in network arrangement, one is able to achieve this objective. The resistors are mounted in a vertical position on the board, meaning that there is space for the free movement of air amidst the components, a phenomenon that may not be achievable with discrete resistors.

Network resistors are capable of value matching. This is because it is dependent on several factors such as temperature coefficient of resistance, changes in the resistor load as well as the sizes of resistors themselves. A resistor network is normally made up of resistors that have almost similar properties, if they are not all similar. Value matching can, therefore, be achieved in a network of resistors because the individual components are similar in characteristics.
