What's this please? (Component Advice)

Perfect!  Thank you!  I knew I would forget something.  They are indeed 1.25mm pitch.

Trying to source a small DC motor (from a coffee frother). Photo shows the style, and it is 24 x 18 (x 31). I can find plenty which are apparently of style '130', but those are typically 20 x 15. Anyone know either where I can get one, or what magic term to use to find one?

(It is being driven from a Li-Ion battery, so around 4V).

Googling for "dc motor 24x18" brings up quite a few results, including e.g. this one as the second result for me:

I guess the shaft diameter will be another critical dimension though -- not sure how many common ones there are?

Thanks. Dunno why I didn't think of that 

Er, any idea how to get Aliexpress back to English? I clicked your link and now I end up with the German site regardless of how I get there

No matter - got there in the end. Clicked the mobile button then in the upper right was the option to go to the global site, and then I could choose my language and that. Phew.

Oops -- sorry about that! I had actually removed some strange "?...GER..." suffix from the link and thought it would be generic. Too much "intelligence" at work behind the scenes at AliExpress...

It's a pretty standard 3-12V (it'll scream at that voltage) motor found in all sorts of things, including Scalextric. Someone recently sold a job-lot on the forum as it happens...

Anyway, obligatory ebay link:  https://www.ebay.co.uk/itm/264063761245



(NAWTS, many other vendors are available)

Thanks, but those are all the '130' style which is too small (20x15 rather than 24x18). Shorter, too.

As it happens, because the right sized one will take forever to arrive I've ordered a couple of 130s with the idea that I might be able to apply packing. They are a push fit into the housing so need the fill the space pretty accurately.

Had the motor apart to see what the problem is (actually did this yesterday before looking for a replacement, of course). Photo shows the literal brushes.

I have a box of bigger motors, all circular so not suitable, which use actual carbon brushes on shaped copper strips. I nicked the brushes out of one of those motors and then cut and trimmed the copper so it would slide in next to the existing non-brushes of this one. Very crude, only held in place by friction and I didn't expect it to achieve anything, but the thing actually works again! I think when this bodge fails (which it must do quite soon) I might try and more sensible adaptation of proper brushes and see if it will last longer then.

And I just pointed out someone not reading a post properly yesterday... my bad

Basically it's a 280-type motor.

Doing a little reverse engineering and I'm fairly certain these are transistors for a switching amplifier but can't figure out who makes them or what exactly they are. Any help would be greatly appreciated

Brilliant, thanks. The shaft is too long but shortening it must surely be simpler than lengthening it

Could be HUF76629D:

[ytterligare]

Can anybody help me identifying this device and give me some specs on it?

Got it on eBay, since I wanted a DC Blocks for my HP 8563A SA, but I cannot find anywhere any specs for this : "TEKTRONIX PICOSECOND PULSE LABS 5500 dc block blocking capacitor 80khz to 26ghz"



The label says "model 5550" indeed and I have also found some docs about the 5500 series, but mine is not there, only a "5500A", in addition the form factor is completely different ( shorter in the doc specs ).

Many thanks in advance !

Hi everyone!
I've got this display, it's a LED dot-matrix 5x7, 9 characters + commas. I have no info on it whatsoever.
Can anyone here recognize it? Or maybe, the calculator model it was apparently taken from?

[NeckLessPhill]

Hello!
I'm looking for any info on AT&T 16801b, 5 pin, found in '96 lexus. It's used to drive a solenoid valve from a PWM signal. I checked AT&T selection guides from '88, '93 and '95 and nothing. Google - nothing. Some people suggested that NEC D16801 might be a replacement, but also no datasheet, no specs, nothing in the selection guides. Might it be a custom part number for toyota? Can anyone shed some light on this puppy?

Hi! Is this a common "component", and does anyone know what it might be called? It's a springy clamp that was strain-relieving the connection of a flat cable to the PCB. The cable was folded around the edge of the PCB, and the cable and PCB were sandwiched by this clamp. Thanks!

Hi all.

I have this Dc connector and DC socket. I would like to know what the name of these connector and socket is please?

Tried googling and similar but don't have much to go on.

The socket is part of a nimh battery pack 4s.
The connector is part of the charger.

Thanks

Steven

I don't know, but it looks very similar to the one end of this https://www.bixpower.com/product-p/cnt-dc23.htm

Hello,
does anybody know this type of through-hole (IR) LED-package?

[HwAoRrDk]

What a strange package. Seems they are inserted into a non-plated through hole and the anode and cathode are the body at each end, which is soldered to the annular pad.
