What's this please? (Component Advice)

Actually, I found it. It's a Diodes Inc SMAJ24CA 24V bidirectional TVS diode. The marking is 'UZ'.

Thanks heaps.  The 24V would make sense, the supply is 24 volts.

Cheers,

What might this be?
It was found inside a Pioneer SA-9800 stereo amp, supposedly serving some sort of DIY modification purpose.
The photos show only 3 wires but allegedly a fourth one had come off.

A thermally operated relay. Probably functioning as a time-delay, although it could be sensing power.

Perhaps speaker de-thump at power up?

Spot on!

Someone managed to dig up this web page confirming what Andy said.

Hi, i know what it is, but I would like to know who made it and where I could find a datasheet for it. I hope this is the right thread for this question, nevertheless.

Looks like a Fujitsu logo?
And since you didn't tell us: It's a CCD.

Got a few of these little guys recently. Apparently pulled out from some equipment, probably military, from the mid 80s. The marking says Plessey GPD340 (or GPD340P). A search for the datasheet came to nothing.
Has anyone come across these displays, or similar? Maybe there's a datasheet, or at least a pinout?

[CJay]

Maybe this guy?

Can somebody tell me what this part is ? Found it on a powersupply board of my dead russian benchtop meter . Could be some kind of regulator IC .

Those are 2 digit LED dotmatrix smart displays - afaik they have an integrated ascii decoder chip . The HP hdsp-2xxx series (e.g. hdsp-2001) should be very similar .  Take a look at this : https://www.digchip.com/datasheets/parts/datasheet/021/HDSP-2001-pdf.php

I used a couple of these about 15 years ago in a temperature controller : https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/1/SLx2016.pdf

Can someone help me work out the connector? I have a Bemex TC303 with no power supply so I need a new plug. It is only a 9V supply so not overly hard to get.

Nope, they're not similar - simply there's not enough pins(only 8 ) to apply HDSP-2xxx's driving scheme, which requires at least 9 pins (5 to drive columns, 1 for data-in, 1 for CLK + GND and VCC). There's got to be some more sophisticated serial protocol like in HCMS-29xx series.

Looks like it's this thing - KPS104G

That's it , thank you      Interresting part - a twin N-FET , never seen that before   

What about the Osram SLx2016 ? This one is also a bit different - only 4 digits and less pins  . . . maybe your 2 digit models need even less pins ? 

At least it's a place to start . But you could be right about a serial interface 

You do not have the instruments they were taken from ? At least one to do some reverse engineering ?

No, nothing whatsoever, that's why I'm asking here.
So far, I've not found any info/schematics/similar models from other manufacturers on the internet. So it seems, shooting in the dark with driving schemes is the only option to display something on them.

Dears, May someone able to identifiy that component (from OWON frontend) it will big help because it need to be repair.
As I know the component start H1K is between the VGA and ADC , what start VUBI is somehow a power suply the ST3FF may also some power supply
Thanks

Thanks, is is strange because the TLV62130 diven a TPS723 (T08I) what is neg regulator...

Read the datasheet, page 25.

"The TLV62130 can be used as inverting power supply by rearranging external circuitry as shown in Figure 40."

hello!! trying too find a chromebook ic bios chip too a chromebook 11mk ee! the bios chip is Winbond ic bios chip W25Q64JWIM do anyone have a copy!! thank you very much!! if you can help!! Thanks!!!

[Yansi]

Any ideas what this buck controller IC may be? It is a ~100V input voltage buck, with 12V output.  Seems to be the typical "floating controller" topology, however it has a rather not typical differential voltage sensing (see the two identical 121K - 3K9 voltage dividers looking at the output voltage). Sry, the schematic is a mess, just as I drawn it from the PCB.
Pinout of the IC is now clear. Marking not so much, someone has scared it with some abrasive tool, so we can be only sure about the first letter, S. Next letter may be L, but it may also be not. No idea how would one search for this. Turned whole LCSC upside down, looking for some SLxxxx chip that would match, found nothing even remotely close. The bottom 4 digits is likely just a date code.
Thank you for any ideas.

Hello everybody,

today, I'm searching for connectors for two generations of mitutoyo touch signal probes. I'll start with the newer version. Does anybody know that connector type or has an idea, which similar connector could be modified easily to make a suitable counterpart?
