Hi,

Anyone have any idea what this is ? It's marked 9FS 5Y

Removed from a Kenwood head unit.

The packaging looks weird, what is there on the right side?

It looks like one of these: https://www.torexsemi.com/file/en/products/discontinued/-2016/53-XC6209_12.pdf

(See page 28)

Yes, it's a SOT89-5 , thanks !

Still not sure what voltage it is, that table is confusing

Looks like...

9 = XC6209xxxxxx series
F = XC6209Bxxxxx product series covering 0.15V to 3.05V in 0.05V increments
S = 2.4V to 2.45V output voltage based on the product series

The 5Y is the lot number.

Hi all.

I´m with an 8116A with an offset at output.

We have found a faulty dual transistor:
HP p/n:1853-0589 -> MD4260

I don´t find anything about this on internet, no datasheet, no spares and no equivalent.

If anyone knows something about it, thanks in advice...

Looks like 2 HF PNP's in one TO77 package: http://transistor-spravochnik.ru/description/md4260/44986

Considering that 3.3V regulator is much more common, maybe it is an XC6223B331PR-G, see page 29:

This TO-92 is in position "T3109" on a Hameg 205-3 oscilloscope's timebase.
The service manual shows it should be a BF256 JFET.

Supposedly defective because I was unable to get the start of the analogue and digital storage traces to coincide, replacing it solved the problem.

AVR transistor tester sometimes shows it as JFET sometimes BJT...

I can't find anything with the actual markings. Any clues?

Could somebody help me identify this component?

This are photos of the output jacks of the Ronan x85 calibrator. The element is between "Output-" and "Output+".

It it a TVS? I can read 50V on it. Does anybody know the particular part?

Axial lead glass ceramic capacitor. Your pictures don't have a good angle on the number that indicates value.

Here's an example: https://www.goldmine-elec-products.com/prodinfo.asp?number=G23426
You can also find them on ebay.

Snadman · « **Reply #1635 on:** November 04, 2020, 07:27:04 pm »

Hey Dave,
I know this is a 4 year old post but I can identify that part for you. It's a triac used in a Lutron TG-603PG 120V dimmer switch. I tried calling Lutron to get any information on it since I haven't found any datasheets or schematics, but they said they didn't have that information. I have one of these dimmers, so if you'd want pictures of the PCB to reverse engineer the pinout, I'd be happy to share.
Thanks,
Remy

It would have helped a lot if you quoted the post you are replying to $:-\$

Not so much a "what is this", but a "where the heck can i get it" question: It's a 5x20mm fuse holder with some sort of extension that makes the entire fuse holder longer. I considered just buying normal fuseholders for their insert, but those are not long enough (the fuse just bounces around inside)...

(I currently have one of those things that gets shared between a Keithley 236 and a AFG, so i need a second one)

Any ideas about this H8Z1K thing? It's in a CE-19 interface for a Xiegu X5105 radio.

Thanks, I found that too but I can't believe that a UHF tuner part would be used to switch a PTT line.

PA0PBZ · « **Reply #1641 on:** December 08, 2020, 10:08:31 am »

I think I found it: IRLML5203

I've never seen markings like this on a capacitor and a google search isn't being very helpful. I have quite a few of them but don't know what they are. All I know is that they were made in Mexico. Any help is appreciated. Thanks

PA0PBZ · « **Reply #1643 on:** December 14, 2020, 01:13:29 pm »

That looks like a varistor.

It looks like a resettable PTC made by Littlefuse.

shig · « **Reply #1645 on:** December 14, 2020, 06:29:41 pm »

Ah ok. I found those. I'm not familiar with them at all. I don't see a chart or legend on how to decipher code on it. Do you know?

Nusa · « **Reply #1646 on:** December 14, 2020, 07:51:08 pm »

The logo is the one used by the TE Electronics/Tyco/Raychem brand for polyswitch devices. Littelfuse acquired that part of them about four years ago, which is why all the supplier links go there now, even if some of the pictures are old.

You can always test one to see what its trip current is. If it's in the label at all, I'd guess that 130 refers to 1.3 amps. The voltage rating is a bit harder to determine.

Two unknown parts from my partsbin:

These two parts have a small note stating they are '7dB attenuators' and the note 'ptt'. The latter gives me the impression it is related to something to do with telephone technology, but I can be completely wrong. PTT used to be the national telephone operator here in The Netherlands.

The circuit looks like an attenuator for a balanced line.

And very generously of the manufacturers, they left it unpotted so it should be possible to measure all the components.
