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. The resistors are usually combined together within the device so as to provide the required resistance. 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 find a whole range of applications in different fields. Those who create electronic products make use of resistor networks in various ways. The network resistors usually have better qualities than the single discrete resistors. Some of the devices that incorporate such networks of resistors include medical, commercial, military as well as industrial devices and machineries. Some of the devices that use network type resistors are sensors and transistors. The way the networks are designed for each application is different, depending on the unique features of the device. A good example is the resistor networks for sensor which require value matching as an important consideration while others do not.
Space can be saved on the circuit board by using resistor networks. It is possible to adopt a single line module arrangement of resistor networks which can be mounted 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.
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 can be explained by the fact such resistors are mounted vertically on the board to facilitate ease of air flow.
Value matching is possible. 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. 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.
