SCA 106
CHMC S19

Yep, CHMC is a Chinese manufacturer and SCA106 seems to be a buck converter. I haven't found any datasheet but a schematic (http://www.df7sx.de/wp-content/uploads/2014/08/radiowerkstatt_schema.pdf).

Hello,

I need some help to identify these two Aluminum Electrolytic Capacitors, the value itself is clear, but I have nothing found to identify the second and third part:

 33uF EFK. 6B5

220uF VFK. 6D6

Is it possible to identify the voltage?


Thanx!
Due to the massive "EEVblog forum attachement bug", I am now using an external picture hoster, till it is solved...

Those capacitors look like Panasonic FK series, E = 25V, V = 35V, 6B5 and 6D6 are lot numbers.

Connector ID question.

Does anyone know what type this connector is. I need to make up another cable and my Google foo is weak on this one.
It's about the size of an SMB connector.
Images attached,


Cheers,
Phil

It also looks like an SMB connector. So why do you think it isn’t?
Or are you looking for the exact model of the male plug?

You can find ready-made cables with smb at both ends, or smb to some of the common alternatives. If your requirements are simple, that may be the easiest route.

Cheers Frozenfrog and Nusa,
I agree that the retaining style is the same as an SMB, but the polarity of the connector is reversed.
I know of RP-SMA but have not found the equivalent in SMB.
I'm not looking for this exact connector model, just a supplier lead for the cable mounted connector style.

After an hour or so of google image search and searching coaxial connector manufactures I cam up empty for this style of connector.
If anyone has a link to this style of "reversed" connector it would be very handy.

Phil

Ok, on closer look, you're correct, it's not SMB.
Looks like MSS instead: https://www.hirose.com/product/p/CL0319-0010-3-40?lang=en  , look at the series catalog linked off that page for mating components.

Wow! That's cheeky. Now, that you pointed out the obvious, I see it.  :palm:
Good catch with the MSS connector!
Seems like I need to get my head checked. I was looking at the images and did not see the difference. LMAO
Also: I never heard of those MSS connectors.

To avoid double post, what sensor (from an iPhone) is this please:  https://www.eevblog.com/forum/projects/reuse-iphone-image-sensors-(camera-only-without-the-whole-phone)/ ?

https://www.ifixit.com/Teardown/iPhone+5+Teardown/10525#s38313

That's a page with a video and many pics.  I don't know where to look.  I know that small flexible ribbon is from an iPhone, it has many sensors on the same ribbon, I linked to the amazon part number of that ribbon, but I don't know what is each sensor.

What does the small yellowish can with a metallic shinny tube attached senses, the one pointed with arrows in my pics?  Not looking for a replace, just trying to learn what it is, because of it's curious shape.

The link should take you to here, where they say it's a microphone:

@tsmith35
On the same black ribbon there is also a small black cube with two bumps, cube that looks like an infra red LED + photo diode ensemble.  I assume that black cube (not well visible in my pics) is the proximity sensor in iPhone 5, and not the metallic thing pointed by the arrow (but I'm not sure).

@PA0PBZ
A microphone makes sense, thank you.

Hi guys, out of curiosity, I tried reverse engineering my flashlight's over engineered driver board to know how it works and because, sometimes the brightness control goes slow responding or the brightness levels goes crazy. (mostly fixed by randomly resoldering all the components in the whole assembly) It consists of three boards in a 3D arrangement. I pretty much reverse engineered the schematic with only three semiconductors I could not identify.

I tried to do a bit of googling but could not identify IC1 the DC to DC boost converter in SOT23-6 which is marked "WB5n3" (disregard the writing  in the schem, I misspelled it there) and appears to have a similar pinout to some LT devices and quite close to a MP3120 but is not a synchronous type.

IC2 is also a SOT23-6 looks like a mosfet, load switch or current sensor? It is marked "D9EA".

Op amp is SOT23-5 marked "SBUS" but I could not find that also. This one is probably some generic low supply voltage rail to rail op amp.

I already identified the LDO as XC6206 252MR

Try this

WB5b3 https://datasheet.lcsc.com/szlcsc/1811081220_Silergy-Corp-SY8120B1ABC_C88474.pdf

Unfortunately, that's not it. I have seen it before posting and it is synchronous buck. The one I'm looking for is non synchronous boost. Thanks anyway  :D

Connector ID please

Trying to identify manufacturer and model series - this is a keyed 8-pole connector, black plastic inner is approx. 10mm and the threaded outside of the socket is 15.3mm.

Thanks in advance.

Looks like these are Binder connectors.
Have a look at their website, probably you'll find them there.

Looks like a plain old microphone connector as used in commercial 2 way radios, ham radios & CB radios.
Basic mics use 4 pin versions, but those that include extra controls use more, sometimes 7, but usually 8 pins.

I thought so at first, but, no, size and pin placing aren't the same and this plug/socket are a higher quality than the usual microphone component.
Might be Binder, have to wade through their catalogue, but at first sight, I don't think so.

Can anyone please identify the 3x3mm IC marked:
DEN
S1A2K

It would make sense that it's a EEPROM but I need datasheet proof.

Thanks a lot gamalot.
That fits the partial pinout I had.
How did you search that? Or was it that  you just knew from using the part before?

No worries. I don’t remember exactly what happened at that time, it seems like that I searched for 'msop8 marking DEN' in Google and found this link:

https://www.digchip.com/datasheets/parts/datasheet/235/ISL90810UIU8-TK.php

Since you mentioned in the previous post that it may be an EEPROM, and the chip I found happens to have an I2C interface, and the pin positions are also matched, so I believe it is very likely that I have found the right one.

 :)
