content: Hey guysPart identification Problem for you:I have a part in a beige single inline package that i can not identify.It does not look like a resistor network though (measuring the resistance between connections is not conclusive more on that later).Also the manufacturers site doesnt really reveal anything of use apart from that the company (Beyschlag) now seems to be a part of Vishay.These are the searches I tried:https://www.vishay.com/search?query=OZ6802&searchChoice=parthttps://www.vishay.com/search?query=0Z6802&searchChoice=parthttps://www.vishay.com/search?query=OZ68O2&searchChoice=parthttps://www.vishay.com/search?query=138537&searchChoice=parthttps://www.vishay.com/search?query=OZ68O2+138537&searchChoice=partalso google seems not to know anything about that part.finally i looked through vishay's resistor, capacitor and RC networks that come in the right form factor and also that is notreveiling anything useful.I got that particular by dumpster diving so I wouldnt feel terribly bad tossing that thing out, it just is a question to me "what is that and what is it for?"The measurements that I said are unconclusive are conducted as follows:Mystery component in a breadboard with wires connected to every single pin the following orderlightblue white orange gray violett brown yellow green darkblue red black (this side has a dot presumably pin 1)then all the following pairs of wires into an mTester one after the other (mostly because a multimeter without croc clips or even changable leads can make your life quite difficult if you have to handle a lot of measurements as they were done here)lightblue - white resistor 684,5klightblue - orange resistor 99.81klightblue - gray ?lightblue - violett ?lightblue - brown ?lightblue - yellow ?lightblue - darkblue ?lightblue - red ?lightblue - black ?white - orange resistor 785.8Kwhite - gray ?white - violett ?white - brown ?white - yellow ?white - darkblue ?white - green ?white - red ?white - black ?orange gray ?orange violett ?orange brown ?orange yellow ?orange green ?orange darkblue ?orange red ?orange black ?gray violett resistor 9238Rgray brown ?gray yellow ?gray darkblue ?gray red ?gray black ?violett brown ?violett yellow ?violett darkblue?violett green ?violett red ?violett black ?brown yellow Resistor 2503Rbrown darkblue ?brown green ?brown red ?brown black ?yellow green ?yellow darkblue ?yellow red ?yellow black ?green darkblue resistor 200kgreen red 200kgreen black resistor 99.95kdarkblue red resistor 200kdarkblue black resistor 99.60kred black resistor 99.95kthe markings read:BeyschlagOZ6802138537 (almost certainly a form of day code)To make matters a bit more representative i have drawn a "schematic" in LTSpice (attachement) that shows the measurements results. Just be aware that the resistors in the schematic are obviously not actual resistors and rather measured resistance values used to represent the measured values so that there may be a pattern recognizable to those that know a bit more than me.

content: QuoteIt is a custom resistor network made for a specific application.QuoteYour measurements are not perfect, you need to account for tolerances.785.8K is actually 684.5k + 99.81k, so lightblue is common (middle point) for white and orange.200k is 99.95k+99.95k, so black is common for red, green and darkblue.
