What's this please? (Component Advice)

That's actually pretty cool! A combination of male faston + solder tabs + board edge connector receptacle.

Yeah its a clever combination of wire-to-board and board-to board. This is in a fuse panel.

Everything else on this board is AMP, and the letters stamped indeed look like a AMP with the 'P' chopped off. I have been on AMP/TE Connectivity site for hours, but cannot find this little bugger.

I am looking to identify the component J02 over on the top right side of the PCB, I think it's a TT8J2 but would like to be sure. It is a PCB from a Sony A7r ii and this component has blown (hole in it).

[gamalot]

Compared with the dimensions given in the TT8J2's datasheet or the pictures from Chinese sellers, the body of the component in your picture looks much wider.

[gamalot]

QS8J2TR also from Rohm has the same J02 mark, but the body is wider.

This seems to be a better fit, just confirmed it's dimensions match with a set of verniers

Can anyone help identify this SOT23 diode, it's just labelled 'SC9J' ?

I don't think it's going to be anything unusual, i think it's just a blocking diode in a charging circuit for a supercap

It's a little blurry, is there a logo in the centre?

[dexters_lab]

I don't think so, it looks more like a moulding mark. There is also a blow hole in it!

I will try and get a better picture tomorrow

A blow hole?  That sounds whaley bad.

It is a SB20-03P from ON Semiconductor, and the package is SOT89 not SOT23.

Can anyone identify the manufacturer's logo on this ceramic filter please

The only reference I can find is to an ebay store based in China, and they brand it as 'CD'  ,  but also give a complete part number LTM50EW as well as other ones with similar P/N's or state the actual  frequency.
ie LTM55EW represents a 455kHz  filter, the M50EW is a 450kHz filter etc. All similar footprint and probably copies of muRata parts etc.

[helius]

That looks like the Cornell Dubilier logo (in one of its variants). I couldn't find any catalogs from them for inductors.

Just a follow up and a huge thanks! The part arrived and it was exactly perfect, brought my A7R ii back from the dead. $30 including postage for the part vs $500 for another (used) main board.

Cheers for the reply, I need 450kHz and 455kHz in different bandwidths, the LTM's are just generics so I avoid those.
muRata do manufacture these parts but I cannot find anywhere that actually sells them and muRata will not respond to any requests I've sent them directly.

TOKO originally manufactured these parts but they had a manufacturing issue and as such nearly all of them are faulty, muRata took over TOKO.

I come across this issue quite often and have to replace 4 different types of these ceramic filters on certain transceivers, others take 2 or 3.
But the only type I have found that seem to be reliable and were available are the ones with the "CD" logo, but I really need to know who they are so I can order more, I was getting these from Kenwood and Yaesu directly but they have run out of stock.

Interestingly the last batch I had that came from Kenwood were TOKO so had been in Kenwoods parts storage for some time as these haven't been manufactured for years. When they arrived the legs were black and you could clearly see the hygroscopic contamination/migration had already taken place which really adds little weight to the DC blocking argument.

I am very happy to hear that your camera has been repaired, and I feel so sad that you have to pay so much postage.

If you know how to buy from Taobao in China, I found a seller for you:

Many thanks for the link, that is really helpful.
I just hope that is actually what they ship, not the "LTM" generics.

I found these on eBay... $16.80 for 20 pcs from China. https://www.ebay.com/itm/203180089011
Also on Aliexpress at $11.99 for 10 pcs. https://www.aliexpress.com/item/1005002674796712.html

Cheers, I had spotted them on Aliexpress, the trouble is it's not that specific model I need there are many different types and I can't always get all of them, some are easier than others. That's why I wanted to find out what the "CD" logo stood for to broaden my search.

M55GW and M50GT seem to be the more difficult parts to find.

So I found some interesting stuff. Not sure if it's helpful, but maybe.

Thank's for the muRata datasheets, there are some full part numbers in those which help me with my search. But so far everything has come back with Obsolute.

I came across that Polish Hesta site a few months back, I got my friend in Poland to communicate with them and they said they do not actually have stock, those pages are just there as placeholders or for Google to find their site
