Toko part

[Chiefy]

First of all hello and thanks for having me.
Wondered if anyone can direct me to somewhere that may have a part i've been desperately searching for?

Its a Toko part #686AIS-1056 0651J1056 or a suitable equivalent.

Any help greatly appreaciated.

Regards

Carl.

I have no idea what a Toko xxx is, but these guys:

JAB Electronic Components for Radio Hams & Hobbyists

sell Toko coils etc, give them a try.

You could try Toko's website, TOKO Inc.. You will find a notice about counterfeit Toko parts in circulation. Hope yours is not one of them.

First thing i did mate.

Approached Toko Europe and Toko Japan.

I'm normally pretty good at getting hard to find parts but this one has me stumped. even my contacts who specialise in this sort of thing haven't a clue.

Thanks anyway.

If you mentioned what it was you might do better, a random part number not recognised by the manufacturer isn't much use.

It's an audio LC helical filter and it is a kosher Toko part number.

I thought you said you're contacted Toko who didn't recognise it?.

Have you ever heard of 'in-house' numbers - where a manufacturer orders items from someone else (like Toko) and has their own part numbers provided for it. This could be the case, so Toko can't identify it, as it's not their part number.

 

[Chiefy]

No i've contacted them but not had a reply yet. It is a Toko part although i cant be sure its current and not obsolete. BEC are looking into it for me as they are a Toko distributor.

If they cant hep me well its back to the techy guys at our end, as i'm just a lowly purchasing and procurement guy.

Sorry i'll read the full post in future lol.

Yeah already checked this out. Looking at other brands of helical filters or should i say our technical guy is.

Does he know what year it is?, they are probably long discontinued by now.

Certainly looking that way 'Doh!' thing is we have to get them, but like i've argued if no one has them and no one can get hold of them what do you do?

I'm sure someone will have a few gathering dust in a corner but i've yet to find them.

Thanks for your suggestions, i'll keep plodding on.

cheers.

Wind your own? - what are they for?, usual uses (in the distant past) were for filtering in very old CD players, or filtering in FM stereo decoders.

Hi

This is basically what it is. **broken link removed** they are actually for a pcb that goes into a fm radio modulator that we manufacture.

Looks like it's intended for a receiver, so has notches at 19KHz and 38KHz - for a modulator presumably a far better active low-pass filter would be fine?.

 

[Chiefy]

If you can think of any i could use then that would be great.

Appreciate your time mate.

Just a 15KHz low-pass filter using an opamp, there are plenty of design programs that do it for you.
