Resistor Networks, Arrays

Resistor networks and arrays are essential components in many electrical and electronic circuits. Their basic function is to reduce or limit the amount of current that flows through a given circuit, but they can also be used to adjust the voltage, adjust the load, and provide isolated grounds. In this article, we will discuss the application field and working principle of 4820P-T02-103LF, a popular resistor network.

Application Field

4820P-T02-103LF is a versatile series of resistor networks and arrays that can be used in a variety of applications. It is designed to support a wide range of embedded PCB electronics, such as industrial, automotive and consumer products, and can also be used in military and aerospace applications. In addition, the resistor networks and arrays in this series are electrolytic hard gold-plated for maximum soldering strength, making them suitable for high temperature reflow processes.

Working Principle

The 4820P-T02-103LF resistor network series consists of an array of isolated resistors. These resistors are connected in a grid pattern and are usually made from carbon film resistors to reduce the total size of the array. When connected to a circuit, these resistors act as a current limiting device, using Ohm\'s Law to decrease the flow of current according to their resistance value. This reduces the amount of current that flows through the rest of the circuit and helps to maintain a stable power output.

The resistor network also functions as a voltage regulator. By adjusting the resistor values in the array, the voltage output to the rest of the circuit can be increased or decreased, allowing for precise control of the voltage delivered. In some cases, the resistor network can also help to reduce noise and improve signal quality.

In addition, 4820P-T02-103LF resistor networks and arrays can be used to provide an isolated ground for a given circuit or device. This can be useful in cases where the device needs a separate voltage or current source from the rest of the circuit. By connecting a resistor network with a common grounding point, a low-resistance ground can be created that is not shared with any other parts of the circuit.

Conclusion

4820P-T02-103LF resistor networks and arrays are a versatile series of components that offer a wide range of benefits for use in embedded PCB electronics. Because of their carbon film resistors, they are capable of limiting current, regulating voltage, providing isolated grounds, and reducing noise. Their design also makes them ideal for high temperature reflow processes. For these reasons, they are a popular choice for a number of applications in industrial, automotive, consumer, military, and aerospace products.
