Resistor Networks, Arrays in a 4108R-1-503LF application field

Resistor networks and arrays are components of circuitry that contain multiple resistors housed in a single package. While both of these components are similar, there is a critical difference between them in terms of the resistance values they hold. Resistor networks have fixed resistance values while resistor arrays have adjustable resistance values. This variable resistance is accomplished through the use of trimmer resistors.

The 4108R-1-503LF Resistor Network/Array contains 8 resistor elements within one package. It is a resistor array that is optimized for use in high impedance circuit applications. The component has a leaded terminal type with through hole mounting. The absolute tolerance of this component is ±10%, and its temperature coefficient is ±200 ppm/°C.

The theoretical and practical reasons for using resistor networks and arrays in circuitry are very different. Resistor networks are used in circuits for their singular, preset resistor values. The purpose is to maintain an ideal, fixed resistance in the circuit. This is most useful in repetitive circuits and sensor applications. The 4108R-1-503LF resistor network/array is used in a variety of high impedance circuits, such as a differential amplifier and a CMOS circuit.

Resistor arrays, on the other hand, are used for their variable resistance. Arrays are also used for their ability to save physical space, as multiple resistors can be housed in one package, instead of mounted across the board. This single-package convenience is especially beneficial in high-density circuits (especially micro-controller designs). The 4108R-1-503LF Resistor Network/Array is designed to provide a single element that is particularly useful in high impedance applications. It is distributed in a large quantity relatively quickly, and it is also very configurable.

A trimmer resistor in a resistor array is primarily responsible for controllable resistance. Trimmer resistors are adjustable, variable resistors, and are not designed to have preset values. They are usually used to set levels, such as amplifier gain, antenna impedance, and 0 dB reference points. The 4108R-1-503LF resistor network/array features a trimmer resistor which provides variable resistance between 0 ohms and 200K ohms.

The working principle of a resistor network/array is fairly straightforward. The component contains 8 individual resistors connected in series or parallel. Depending on the resistors being used, the total resistance will vary. In the case of the 4108R-1-503LF, the total resistance can reach up to 200K ohms. The resistors in the network can also be used to fine-tune the resistance of a circuit, by using trimmers to adjust the individual resistors.

In conclusion, the 4108R-1-503LF Resistor Network/Array can provide a highly useful single-package solution to high impedance circuit needs. It is useful for a variety of PCB designs, especially for microcontrollers, as its adjustable resistance levels are perfect for space and time-sensitive design needs. The component is easy to mount and configure and can be used for a variety of functions such as setting amplifier gains and antenna impedance levels. This component is an invaluable tool for anyone dealing with high impedance circuitry.
