743 Series, Resistor Networks, Arrays

Resistor networks or arrays are electronic devices that consist of two or more resistors packaged together either in a surface mount or through-hole format. These resistors can be isolated from each other or connected in various configurations, such as an R2R ladder (digital-to-analog converter), bussed arrangement, voltage divider, dual terminator, digital-to-analog converter, or decade resistor circuit type. The resistor networks offer the advantage of having multiple resistors integrated into a single package, which simplifies circuit design and saves valuable board space. Each resistor within the network can have its own distinct resistance value or share a common value, depending on the specific configuration and application requirements. The available resistance values in resistor networks can range from zero (jumper) to 5 GΩ, catering to a wide range of applications. Additionally, these networks come with different tolerance levels, typically ranging from 0.1% to 15%. The tolerance indicates the permissible deviation from the specified resistance value. Resistor networks find applications in various electronic systems, including telecommunications, automotive electronics, industrial control, and many others. They are commonly used for precision voltage division, impedance matching, signal conditioning, digital-to-analog conversion, and other circuit functions where multiple resistors with specific resistance values are required. In summary, resistor networks or arrays are electronic devices that combine two or more resistors into a single package. They can be configured in different ways and offer a range of resistance values and tolerances. These networks are widely used in electronic circuits for functions such as voltage division, impedance matching, and digital-to-analog conversion, providing convenience and space-saving advantages.
