Resistor Networks, Arrays

1. What are Resistor Networks, Arrays?

Resistor networks/arrays are miniaturized components consisting of multiple independent resistors integrated on a single substrate. Based on their topology, they can be categorized as follows:

Series Type: All resistors are connected end to end (e.g., DIP-8 package);

Parallel Type: All resistors share a common terminal (e.g., SOT-23-6 package);

Hybrid Type: A composite circuit structure (e.g., bias networks in integrated circuits).
