Resistor Networks, Arrays

77061154 is a resistor network or array with diverse applications. Resistor networks are composed of resistors wired together either in a series or in a parallel circuit. The resistor networks help to produce a desired current or voltage. By having the current or voltage of one circuit depend on the other, these types of networks can be described as non-linear or linear resistors. While they are not limited to these two categories, these are the two most commonly used.

Applications

Resistor networks serve a variety of applications, ranging from film processing equipment to data protection circuits. They are used specifically to satisfy many design requirements such as limiting current flow, setting standard popular resistance values, providing level shifting, dividing the circuit voltage, or providing protection in case of an over-current or short-circuit. Resistance networks have the advantage of being able to be easily changed to provide different solutions to the electrically driven problem.

In film and photography, resistor networks are used to control the level of redox potential of the photographic solution. This allows for a longer development time of a negative before being overexposed. The variety of different products available to photographers is a testament to how useful these networks are in processing different types of film. They are also used in digital devices to protect circuits from power surges, noise, or unexpected voltage drops.

Resistor networks have many different applications in the industrial field. They are often used as voltage dividers, to sense level changes, and for motor control. Resistor networks can be used to control power to motors, to provide overload protection and help reduce energy losses. They are especially useful in microprocessors and microcontrollers to properly set the timing of electrical stages.

Resistor networks are also used in medical applications. Specialized resistor networks can be used to assist with the timing of pacemakers and wound dressings, monitors for breathing and heart rates, and also for sensing brain waves. This is another testament to how versatile these resistor networks can be in solving electrical problems.

Working Principle

Resistor networks typically contain two to many resistors in series and can be linear or non-linear. Linear resistor networks function in a similar way to an individual resistor, with the total resistance of the network being equal to the sum of all the resistors. Non-linear resistor networks make the current or voltage of one circuit dependent on the other, which is what is most commonly used in engineering.

One of the important characteristics of a resistor network is the fact that it will conduct equal amounts of current through each component of the network. This is because the total voltage of the network is equal to the sum of all the voltages in each branch of the network. This means that if a voltage of a certain magnitude is placed on the input of the network, the voltage across each resistor will be the same. This makes them ideal for applications such as voltage dividers, which need to output a certain voltage.

Resistor networks also have the ability to compensate or reduce changes in component values due to environmental conditions. This makes them very useful in applications where the resistor values must remain consistent in a harsh environment. This compensation can be accomplished by connecting two or more resistors of a specific value in series or parallel.

By understanding the different applications and working principle of resistor networks, one can design and select the most suitable network for any particular application. Having knowledge of how resistor networks work and their different uses will help in the design process and save time and money when sourcing components.
