To make a smaller PCB/Circuit Board resistor network’s are widely using in electronics field. Some engineers use a set of identical resistors in a package it is known as Single-In-Line (SIL) resistor network. The network resistor basically a package of some resistors. One end of each resistor is connected all the other resistors and this is the common pin, identified as pin 1 and has a dot on the package.
The network resistor’s are very much reliable than a usual resistor. If you want to check value of the network resistor you have to find out number 1 pin. All values will be identical when referenced to this pin.
