Advantages of Using Resistor Networks When Designing 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. 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. 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. Highlighted below are some of the benefits of incorporating resistor networks into circuit designs.

Resistor networks find a whole range of applications in different fields. Resistor networks find a wide range of applications across the electronics industry. This is because they have superior qualities to the individual discrete resistors. Some of the devices that incorporate such networks of resistors include medical, commercial, military as well as industrial devices and machineries. 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.
They are capable of saving space on the circuit board. When thick film resistors are arranged into a network, they are constructed in single in-line modules vertically. 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. 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. 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.

It is possible to do value matching with a network of resistors. Value matching is a function of numerous factors such as the coefficient of temperature resistance, size of the resistors as well as the fluctuations of the load across the resistor. 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.
