Additionally, if you go to the manufacturer's website, they often have a link somewhere on the part's page that will list known distributor stock. This will show you which distributors have that particular part, and how many they have. It's not 100% accurate as it's not necessarily updated in real time, but should be within a day or so. I've found it to be a big timesaver when looking for oddball stuff in that it can save you the trouble of having to look everywhere as it at least gives you a feel for who doesn't have it...

@Nusa: Thanks for the research! I also found the 60-pin part, via Octopart, in stock at Arrow.

@Cubdriver: Yeah, checking the manufacturer's page for "how to buy" is something I do a lot too. Sadly, the 3M website is pretty crappy in that aspect and I could not find any information about distributors on their product page.

Could anyone find out what this is? A tranistor? It was in the dumpster from my school and i can't find any information in the internet. It could be from the 70'ties or 80ties.

Can you show the other side?

Pluscrafter · « **Reply #1504 on:** April 28, 2019, 06:02:47 pm »

Its a three pin device and it maybe a transistor(pnp) because you can measure the typical voltagedrop over the pins.

It sure looks like a transistor. I wonder if the first M is the Motorola logo, and I'm also not sure what the second letter is. I think the last line is the date code, week 36 1981.

I think "MHH" are the letters.

That appears to be a 2N1614.

So 'MM', didn't see that...

Thanks. I though that were "H"'s.

It is a Motorola 2N1614 transistor in a TO5 type case. Since the Jedec system prefexed all transistors with 2N it was common to leave it off , just like the European and Asian transistors were marked 2SA, 2SB, 2SC and 2SD the 2S was usually omitted. That is what many small signal transistors looked like in the early days. Just google 2N1614 and it pops right up. Case shapes are assigned an industry number. The large TO 5 is not seen much any more for small signal transistors.

Hi

This is very close (in shape of the metal shroud) to a USB mini plug.
It has 11 internal pins, not including the metal shroud, so 12 conductors.

It’s a Yaesu handheld transceiver programming cable, so if the part is some stock component, it would be far cheaper to make one than buy it.

Anyone find it familiar?

I’m quite sure that’s it, but still can’t find it to buy!

Well, the article gives you many informations:

Quote

Under the model designation 020036MB011M50XYZR, Suyin announced two greatly miniaturized surface-mount I/O connector receptacles with a design that is similar to the Mini-USB format.

[...]

These receptacles are supplied in tape & reel packaging; the mating plugs are supplied on trays and are available in minimum order quantities of 80,000 pieces per year or more.

Visit Suyin at www.suyin-europe.com

Just visit them and ask where you can buy those things.

@rt · « **Reply #1516 on:** May 18, 2019, 03:00:52 am »

I did find a supplier with minimum order of 37.
Looks like I’ll be selling some cables

Thanks.

Can someone tell me what this is next to the piezo speaker? How does one go about testing this part?
Thanks in advance!

Hey everyone,
just got my hands on a few of those 1Ohm .1% shunts. since it has been discontinued quite a long time ago (our purchasing department said around '93) I can't find any datasheet. Since I know where this was used I assume it is a quite nice shunt, but I would love to know more about, especially in regards of stability over time and temperature. eventually someone knows anything?

On the thing it says:
BADER C51b
BMN 1/1 1R00 0.1

Edit: Just found another part in the pile which is supposedly an equivalent. It is an Isabellenhütte S45 A-N-1R00-F1-K2-0.1. Looks identical to the BADER one, just different marking. If nobody knows anything I may phone the guys at Isabellenhütte, AFAIK they are quite friendly

Ubernuton · « **Reply #1520 on:** May 28, 2019, 09:06:55 am »

Any idea what this is? I'm fairly sure it came out of an old stereo.

PA0PBZ · « **Reply #1521 on:** May 28, 2019, 09:48:22 am »

Looks like an IF filter, first I thought for the FM IF (10.7Mhz) but the 459 suggests it's for the AM IF.

[Edit] See here: https://www.changpuak.ch/electronics/ceramic_filters/muRata_Filters.pdf

Ubernuton · « **Reply #1522 on:** May 28, 2019, 10:55:59 am »

That looks about right. Thanks

@rt · « **Reply #1523 on:** May 30, 2019, 05:03:39 am »

The part next to the piezo speaker is probably a diode to prevent reverse current damaging whatever is driving it.

Looks like a glass cased MLC capacitor.
