Dear friends,

I am facing trouble about resistor network. I searched by net but not found, it is 8 pins SIP, pic are attached.

Could also try RS Components (usual disclaimer). e.g.

It appears to be a Vishay Sfernice part, and the "CNS" means it's a custom part, which explains why it doesn't have any value printed on it. If you contact Vishay they may be able to provide the details of the part based on the "CNS 328" part number. Here's a link to the datasheet where I found the information below:

Gosh. I find it odd that anyone would need a custom SIL network like that. Maybe from the days of maximum miniturization but before surface mount.

I've used a custom SIL network for gain accuracy over a wider temperature range. The absolute value of the resistors still drift but with all resistors at the exact same temperature (outside of self heating) the gain remained close enough to the exact same value.

At LN2 temperatures this didn't work because the semiconductors shutdown but that's another story.

You might get an ohmmeter and see if you can deduce what is inside...

Reverse engineering are we?

You need to determine what type it is....

Then maybe build or buy, depending on quantity needed...

We have checked as bussed and independent. This is not that. This is seems to be custom.

Is it more like a voltage divider network? Such as something a range switch would connect with?

What resistance readings did you get? Like resistance across pin 1 and pin 2, across pin 1 and pin 3, and so forth.

Maybe if you tapped it gently with an exploratory tool it would give up its secrets....

Use a bigger one. Use more than required force to print the object on a page of blank printing paper.

I also went to BFH Institute as did Tom.

BFH's or resistor networks?
