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. 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. 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.
There are numerous different applications for resistor networks. Resistor networks find a wide range of applications across the electronics industry. 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 also used in transistors, sensors and many other devices that require resistors. Different gadgets require that the network resistors be designed in different ways to mirror their unique properties. Resistors used in sensors, for instance, make use of value matching, which is not so much important for the pull up/pull down applications.
Space can be saved on the circuit board by using resistor networks. Vertical mounting of single line module networks of resistors is possible. The kind of mounting adopted for this design of network resistors takes up minimal space as compared to the mounting of the individual resistors with the same effective resistance. Greater density of packing and mounting the resistors can therefore be used due to limited
space taken up on the board.
Heat dissipation from the circuit is improved when resistor networks are used. Heat dissipation is a major function of the resistors in an electrical circuit. 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 can be explained by the fact such resistors are mounted vertically on the board to facilitate ease of air flow.
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. Value matching can, therefore, be achieved in a network of resistors because the individual components are similar in characteristics.
