One more to add:

http://www.datasheetarchive.com/

I am fairly new to finding out what part I have. I like salvaging items from boards.

For example I have a part that has d2396 on one line. On a lower line are a  J and a strange T 08 and at the top it looks like an R.

When I did a search for d2396 I got d2396 from Bristol Electronics and I also found a    2SD2396K from Digikey.

Can you tell who made the chip?

Is there any consistency on the markings?

P.S. I saw a video with a guy reviewing a electric vacumn desoldering gun. It made short work of removing chips, etc.

Is there somewhere a look-up-table for all the abbreviations used in datasheets? I get Vr, If etc. but I am quickly lost after that.

Usualy if a datasheet is not on a major vendor website, it means it's long obsolete.

If you can't find the datasheet, you might be able to find the databook here at Internet archive. There are many manufacturers, quite a few years including some from the 60's.

archive.org

Or just google Internet Archive.

I downloaded a bunch of databooks. Motorola, texas Instruments, Philips, Toshiba, Hitachi, Sony, Panasonic, etc., etc., etc.

If you use a tablet, download them to a large USB stick or memory card.

Hello ;

This is a 10 years old post and still alive until now and I still believe that alldatasheet website is the leader source for components datasheets  ;)

Is it uncommon or unusual to just contact manufacturer (through email) and ask them for data sheet?

Iv got ATX power supply that i want to fix and modify, but can't find datasheet anywhere.

Doesn't look like it's been mentioned so far - I personally reccomend www.manualslib.com. I frequently find manuals I need for work on there, and the layout is reasonably ok.

Not unusual at all. They're not obligated to be helpful, but most big companies will try and help find what you're looking for (then try and sell you stuff).

As a novice I like the old data sheets from the likes of ON Semiconductor and Texas Instruments. They have the usual data but then they go further into example circuits which I find very handy. The newer data sheets don't have this so much.

I am noticing that a lot of the spammy web sites are creating phony PDFs to take advantage of those of us who search for datasheets using Google's "filetype:pdf" advanced search parameter. One way which I now use to defeat these spammers is by adding "absolute maximum" (in quotes) to the search criteria. I find that this phrase is almost universally present in electronic component datasheets.

Also, if you wish to restrict your search to a particular site, use something like "site:ti.com" as a search parameter.

It is shortcut from "TEchnika SLAboprouda" freely translated as low current technology. The parts are common on east Europe markets (communist block). More details in wikipedia. I'm not sure if there is something what make sense to mention, since they have produced a lot of copies of western parts and can be directly exchanged with originals. Some have unique name, but for example logic ICs used same numbering.

Is there such a website where you can upload your own data manuals for others to download?
LOTO focuses on virtual oscilloscopes, we strengthen software and streamline hardware to develop oscilloscope and peripheral modules. Powerful software and rich scalability of hardware are the customer values we continue to pursue.

If you want to search for PDFs at the Wayback Machine, replace "%s" with your search term.

https://web.archive.org/pdf/search/%s

For example ...

https://web.archive.org/pdf/search/lm339

You can also create a custom search engine in your browser using the above URL.

RELIABLE E.S.R. LIST ( ELECTROLYTIC CAPACITORS)
« Reply #95 on: March 14, 2024, 12:24:14 pm »
Hi Guys,
I was literally going to create a new post and then i came across this database related thread and thought .."Perfect".

Let me explain what was happening,
Short Explanation : I'm Posting a RELIABLE E.S.R. List

Granted Beginners won't understand, so.. here's the explanation before the list.

SUBJECT : GAINING RELIABLE E.S.R. VALUES TO KNOW IF A CAPACITOR IS GOOD OR BAD

HISTORY : I'm 50 years old, I have used this list for at least the last 40 years and i have not had to update it in the last 10 years at least.

Let me explain FOR THE NEWBIES

When Measuring capacitors when fixing stuff,  You want to know the capacitor works.
so...
- You may crack out a continuity tester (This is a very poor way of testing a capacitor)
- You may crack out a Digital Multimeter in Capacitance Mode and do it that way (Also not very good, and doesn't work in Circuit)
- You may even buy an ESR Meter or component tester and it has a very tiny ESR list on it, or someone may have told you that
   "Just keep it under 0.2 Ohms and you'll be right"  well that's not correct either and the list you get with the ESR tester is not a very good
    list

You're going to quickly learn
1. You need to test the caps reliably so that you don't install a shit capacitor in a unit thinking it was good and fixed because
    this will cost you time and money

2. You need to know what value to expect NO MATTER WHAT THE CAPACITOR VALUE IS

Now yes you can download the datasheet, but
- You need to get the Exact Brand
- The Exact capacitance value
- The Exact voltage rating
- Th Exact Tolerance Rating
- The Exact Physical size

Because all of these things can vary the E.S.R. of a capacitor.

NOW HERE IS WHERE I SAVE YOU DECADES OF HEADACHES AND RESEARCH
Once upon a time i was confused as hell and i said this to myself ..

1. Given that different brands of same cap values can have Different E.S.R. Readings.  How do we unify this a bit better so we don't have to store thousands of readings for 1 capacitor value ?

2. Do i need to have a list for EVERY SINGLE CAPACITOR VALUE OUT THERE ?

ANSWERS
Answer 2 First..   No you don't need to have in your list Every single cap value,  You just need to have EVERY VALUE for the one's that you commonly use in your common applications and fixes. 
              you will come to understand that fixing monitors are going to have certain common cap values, then.. fixing Laptops are going have different ones, Fixing audio amplifiers are going to
              different one's again.    Let your electronics journey organically dictate which it is.

Answer 1 - Ok, so what you do is this (i have already done this) so let me explain it.

Let's say that we have 680uF capacitor , 100V Rated
Lets say the manufacturer datasheet says that the ESR should be 0.3 Ohms
OK, well all we need to know is.  WHAT VALUES ARE WE GOING TO ACCEPT IN OUR WORK
Because this is all that is important

In my list for this capacitor i have the following values  0.07  0.13   0.18
LET ME EXPLAIN HOW THIS WORKS

the lowest figure is  THE LOWEST MEASUREMENT I HAVE EVER TAKEN ON ANY CAPACITOR IN MY LIFE FOR THAT VALUE
the highest figure is  THE UPPER LIMIT THAT I WILL ACCEPT AND WON'T GO BEYOND and that i feel confident with
The Middle figure is the average of ALL CAPACITORS EVER TESTED IN MY LIFE FOR THAT VALUE


so here is how this list was created.

1.  you need to have some high E.S.R. values and blow shit up to know "Ohh right, so i can't go that high"  LOL

2.  if you remove say 10 capacitors from a board, Chances are they are not all going to be bad. What you do is.. Measure the ESR of all them and make sure they are pretty close to each other
     in value of ESR (This is a good starting point).

AS A PERSONAL DECISION (and you are free to change the spreadsheet in anyway that you wish)
1. I didn't like using 0.0 as a minimum because, it goes without saying that that's a good value, I NEEDED REAL VALUES
2. I needed to know the Max that WOULD ABSOLUTELY GUARANTEE A FIX and that i didn't have to worry about it.
3. The Middle is the AVERAGE (Total number of capacitors tested and their total values added up divided by the number of capacitors tested.

Now when you get a new batch of say 20    but you have a mid reading of 0.13  you do the calculation based on 21 capacitors and the first one had an ESR of 0.13  this way , You are including every single capacitor that you have ever included in your list

LASTLY... THIS LIST GETS UPDATED LITERALLY EVERYTIME I USE OR TEST A NEW CAPACITOR thus over time it gets checked for accuracy

Now, all the values i have in this list ARE ALL THE VALUES I HAVE NEEDED TO USE IN 50 YEARS and all the ESR values are the ESR values that have always guaranteed me a fix

if you get to a point where YOU CHOOSE you want to increase the max value.......... THAT'S FINE, Just test it that it does work on the product safely.  In some cases i do concede that the max value could be much higher according to the manufacturer datasheet, it's just that i have never tested a cap that high,  and thus never had the need to increase the max value.

so with that being said and now you understand how the list came about

HERE IS THE LIST IN TEXT FORMAT

AND I HAVE ATTACHED A SPREADSHEET VERSION OF IT AS WELL, Feel free to use it anyway you like. I literally had to organise all my caps recently, I have 10,s of thousands of them, but only these values. so i figured i would share the list with the community

EDIT :  1 last thing
If you ever come across a value that is not in this list what you do is this

1. Enter the value in the correct position
2. test the capacitor you have
But the obviousness of the problem is... HOW DO YOU KNOW WHAT THE CORRECT VALUE IS ?

Answer : Look at the ESR value of the caps above and below it as there is direct correlation when increasing or decreasing in value
between capacitance and voltage.  so just gets the values of the caps above and below, after that, when you get more of that value
cap you can test them against the value you currently have an update it

Lastly you can go to one of the suppliers and get the datasheet and look up the ESR value if available
