Identifying SIL BUSSED resistor networks

[exxos]

This seems to be confusing some people so this is how to read the resistors.

A typical 9 pin SIL bussed resistor network will look like this..

A typical format is as below.

You may observe they may be more or less markings than is on the physical package.

For example the image shows only "A 222G" . The important thing is the "A" which denotes bussed and the "222" figure. Where is quoted in ohms as 2200 (2.2K). The first two digits nominate the number and a third digit nominates the multiplier. So again "222" is "22" with 2x zeros (00) in other words, 2200.

Another common one is 103G or 103J. Where the last letter is the tolerance and is not critical in general. So again we have "10" and "3" zeros, which make 10,000 ohms or 10K ohms.
