Thanks for everyone's input. I have figured out that the values I listed above are correct. What i did is put single resistors in place of the resistor pack. I have not figured out who makes this part. but since I am redesigning the board it doesn't matter. I will just use the signal resistors. Thanks again for the help.

I will try to put a picture up. to answer some of your questions yes the part is out of the board. I have measured it this way and had another person measure it as well. and he got the same results. I have found that the board was made in 1987 by Kardex.

Yes, picture of part is very essential. Also, what is surrounding circuit? You may be able to narrow knowledge gap from this.

You were testing these resistances with the part removed from the board I trust? Otherwise you will see all sorts of strange characteristics due to the connections between this component and the others, especially the capacitance and diode characteristics between the power lines. The part number certainly sounds custom to me - if there is no manufacturer mark then that is a pretty good clue that you won't get this part anywhere else. Why are you wanting to know this - are you reverse engineering a board or trying to replace the part? If you are replacing the part that might indicate that its electrical characteristics are no longer the designed ones so measuring it now may not be too useful!

It seems like some kind of custom resistor network. You might be able to determine whether or not they are isolated. I think CTS use to make an rnet in a blue package. Vishay had (has?) a beige color for surface mount. I'm not sure what color their DIPs were. If it's an old part there's probably a good chance it was made by Vishay/Dale, Bourns, CTS, or IRC.

Those measurements make no sense for a resistor pack in isolation, common connection, or parallel termination configuration. Do you have any context on the part's origin? How old is it? Where did it come from? What equipment was it installed in? Is the package material plastic or ceramic?

I have a 16-pin dip part that i believe to be a resistor pack.

Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
