Can anyone enlight me what is this DIP device?
I guess it is a solar cell. I can measure 200mV from the bottom-left pin vs any opposite pin, but why a solar cell need so many leads?
Thanks

i would imagine to keep the esr nice and low, those puny panels generally have esr's higher than alkalines on there own, so a number of them in parrellel would drastically help lower that,

Linear photodiode array. Multiple photodiodes so that you can focus an image on them and use in a line scanner. Probably used in an older shape sensing detector. or as a detector for a low light diffraction grating

Can anyone shed any light on this monochrome imaging sensor? It's Hitachi HE98268, from the 1980s. A datasheet would be awesome to find! 8)

128x64 LCD screen.

I have couple of 128x64 chip on glass LCD screens. It uses a 30x0.5mm FFC/FPC connector. My first guess was something like the SPLC501C COGs.

e.g. http://www.newhavendisplay.com/nhdc12864mznswbtw-p-664.html

The pinout differs.

The only markings:
WD-G1206VC-7WNNa
02064611AD
14C23/03


It's probably something custom and I won;t find anything, but I had to ask.

Hi,

Today while trying to clone my navigation HDD to a SSD from NTG2.5 Mercedes COMAND unit, I've managed to break the connector that goes to the motherboard when I've removed the original drive.
Does anybody have a clue on what type of connector is this?

I've searched the web for hours and didn't find anything. I've found something that looks almost the same but they have non-symmetric keys to match the male-female, but this one does not have any key. The key is that you can mount the whole device in a single way.

I've attached pictures with it broken and "mounted".

Looks to me like an inductor ... 47mH perhaps.  Grab a multimeter and test it and you'll know for sure.

Can anyone identify the smd components in the middle here. They're in parallel with a solenoid (one per solenoid) and have short circuited.

Also what is that package called?

Diodes, the package is MELF. You can use any 1A diode like a 1N4004 in replacement, or a surface mount one rated at least for 1A and with a reverse voltage at least double the voltage of the power rail.

Any one have an idea as to what this is, it's rated as 50 ohms and looks like a BNC but it is much larger than a standard BNC socket.
It is slightly smaller than the C connector oat only 13.6 mm dia. It is silver plated, I have looked on line and cant find anything like it.

It looks a lot like it is to an N connector, what BNC is to TNC.

That is, similar, but quick-connect instead of threaded.

I know there are some quick-connect versions of the N connector, but my google-fuu isn't with me today, so couldn't find anything that matches exactly.

It turns out they were MOV's but serving the same purpose. I replaced them all with diodes. I've since found out people replace them with 1N4148's but they're surely under spec'd?

My turn!

Looks like a fuse holder (notice the amp's labeling), since it is part of a mains extension, but the thing that i thought were the screw to open the compartment is glued and doesn't comes off  ??? ... Also it has some kind of button that doesn't do anything when pressed. This "button" thing don't latches, it's more like a tactile switch. 

Is it some sort of circuit breaker?

I'd be surprised if it was not a circuit breaker. The over current condition will trip a latching relay, interrupting connection until reset. I'd imagine it should be put in as a module and not soldered on to as such, but I haven't a clue what electrical codes are anywhere.

It's a chinese mains extension... No surprises it's mounted like that, but I think this circuit breaker is a nice touch to a mains extension.

Thermal circuit breaker. Inside is a bimetal strip that carries the current, and when it gets hot from current it eventually moves enough to overcome the latch holding it closed on the other contact, and moves to the open position. When it cools it stays open until the button is pressed which pushes it back past the latch to closed again. If they are used a lot ( or with time and many near trip cycles) they have a nasty tendency to arc at the contacts when loaded.

Thermal trip. The button feels like it does nothing most of the time but when it trips it pops out further, you will then find when you push it that it has some resistance and  most likely feel or hear a click when pushed all the way in.

What is the little black device? I originally thought a cap but I'm not sure.

... A theme!

A quick search for AUPO A4-F lead me to the following:


(cached result linked as main page seems to not load:)
http://webcache.googleusercontent.com/search?q=cache:http://www.aupo.com.hk/egproduct/af.htm&hl=en&prmd=imvns&strip=1


It appears to be a thermal cutoff protection device (aka thermal fuse?) @ 126±2C fusing off, 107C holding temp

Help getting some data for this chip ATMLU020-16B. The supplier told me that’s an ATMEL 24c16, is this ok?

Thanks in advance.

An easy one, hopefully.



The orange blobs at the front. They're capacitors, but what sort?

This is on the PCB of my FLUKE 75 multimeter (which is currently not displaying everything it should).
Is it a cap?
Should that split/crack be there?
What do those numbers mean?

I like this meter and I'd like to revive it but I'm running out of parts to replace. Any thoughts?

Thanks!
