Great Find! Now I know where to look - searching for "Position Sensitive Detector" gives a lot of good articles.
Hello Forum
I just spend the whole yesterday afternoon to find a mating connector that can be mounted on to a plastic Housing, but i was unable to find the right one ( If there is any).
I have contacted the Manufacturer of the Rollerdrive but they just replied that i should buy their controller.
Attached two pictures of a cut of one and a link to the PDF from the Product where the connector is attached to. (The DIP IC is just for size reference)

Hello all,
I am trying to find a STMicro part from its markings but I'm having no luck at all. It is a TO-220 part with markings "130 082" on the first line, "GKO5D VU" on the second line, and "CHN 209" on the third line. I've searched everywhere on the internet that I can think of but nothing is found for the part. I've also inquired on the STMicro support site(twice even) and have gotten no response from them.
Any ideas on the ST part number and date code for this part? I have a bunch(meaning a couple hundred) I'd like to sell so anyone who knows, and can help identify, will get first dibs on purchasing at a great discount!
Any help is appreciated.
Thanks,
Dave
It seems likely it is a "house number" and not a commodity ST product number.
So it is either a regular ST part with the customer's special inventory number,
or else it is a custom part (either custom designed, fabricated, tested or packaged).
Do you have one of those "$20 LCR ESR Transistor Diode Checker" gadgets?
https://www.eevblog.com/forum/testgear/$20-lcr-esr-transistor-checker-project/Chances seem pretty good that you can plug most any kind of unknown part like this in, and it will identify what it is, and the basic ratings.
If you don't have one of those things, I very strongly suggest getting one.
Thanks for the reply Richard. You may be right about a non-standard part number.
I do have one of that type of testers but I was hoping to be able to link it up with its datasheet.
Thanks again for your help. The search continues.......
Thanks for your answers. It seems like it is in fact some sort of position sensor. What would something like this be used in? I am assuming that for anything that wants to move across and get detected the travel would be very small. Any ideas where this might come from or be used?
Quad photo-diodes are used in Atomic Force Microscopes to detect when the tip gets close to the surface and regulate the Z-piezo.

These linear photodiodes / phototransistors were used in early optical mice with a printed grid. The 4 outputs move in quadrature when a shadow passes over the sensor.
I maybe peeing into the wind here guys but if anyone can help me, you can. I've got an IC here from a microscope camera that popped on me a
while ago when a DC-DC converter failed.
The chip in question is a 32pin QFN showing the following codes: ES 2A / GOR
EDIT:::: It's ok guys I think I've found it .. ( Richtek - RT9992ZQW ES )
Thanks for that Belgarion

It looks like house numbering - but at the same time the 08 and 05 make it look like its a 5 volt regulator (maybe a 7805). If you show us the circuit you found it in, you might be easily able to tell what it is. Also, if it is indeed a regulator,
A standard 7805 e.g. from ST (got from Mouser) is numbered:
First line: L7805ACV
Second Line: GKDSL V6
Third line: CHN 506
So that tells me that the second and third lines do not really give you any helpful info. With 130 082 on the first line, it looks like it is house numbering. Now, the cheap ebay testers WILL NOT be able to tell you if this is a Regulator e.g., but if it's a Triac or transistor they will - not that that is very useful! Why don't you just start checking it out with a multimeter for diode drops etc.? BTW. if this was taken from a circuit and if you show us the circuit the part was on, it will be really easy to guess.

The device in his pic looks brand new so I guess he got it by itself or in a grab bag.
Hi all.. I'm assuming this is a Ti DC-DC converter, It comes from the small PSU for a microscope camera. However I can't seem to find a replacement
or datasheet for this exact one.. It's coded.. VUBI, Ti33, ADD1.
Could anyone please tell me what it equates to or where to find a replacement?
Many Thanks
This is the PSU it's from.. Yes there is 1 blown trace, but luckily it's not used
Could anyone please tell me what it equates to or where to find a replacement?

Thanks PA0PBZ. I had seen datasheet previously.. Do you know for sure that.. that is a direct replacement for the VUBI Ti33? I only ask as the part numbers are totally different and I don't have a
datasheet of the VUBI chip to compare it too?
Many Thanks
You don't have a "VUBI"
You have a TLV62130ARGTT and the SMD marking code is "VUBI".
Did you miss the table on the addendum page 1?

Yes I did miss that, thank you for pointing me at it
So what is the Ti33 number as I have seen other IC's using the 'VUBI' top line but then letters like.. Ti55, Ti48, Ti36 etc.. Are these all the same TLV62130** ?
Thanks
VUBI means TLV62130ARGTT regardless of the rest of the nomenclature.
VUBI is just the "nick-name" for TLV62130ARGTT.
"Ti" sounds suspiciously like "Texas Instruments"
The two-digit numbers are probably an encoded date code.

I appreciate the help Richard. Thank You.
Google reveals: http://www.ehow.com/info_11386135_sh-capacitor.html
"SH" appears to mean "self-healing".
Interesting! I just assumed they were some variation of an electrolytic.
I wonder if the current rating is the maximum current they can pass and still operate, since it appears to relate to frequency. I have a high voltage (400v DC) lab power supply project, I wonder how well these would fit the bill.
Richard you should have tagged the ehow link as Not Safe For Work!
That article talks about "metal foils exposing themselves to each other"
I also find "a thin layer of metal vacuum replaces the aluminum foils" quite shocking. Don't play with "metal vacuum" kids!

Yeah, brand new. I have 490 of them and really want to do something with them!
