Who else besides Toko does coils with tuning slugs?

M

Malcolm Reeves

Hi,

Who else beside Toko manufactures coils with tuning slugs? I'm
looking to design an LC filter and need a coil with a few windings.
Toko data is very thin (non existent) and I'm currently waiting.....
So if there is another manufacturer with good data, good supplies,
etc. they could get my business :).

Coilcraft has slug tuned coils. Reasonable data, good sampling and quick
delivery on purchases. The 164 series is a 5mm vertical coil and the 148
series is a horz. coil. They make others.

Toko used to provide a lot of data, but it's difficult to find in
English. I had Japanese help about 10 years ago. If you care to email me
with what you want, I'll see if I can help. No guarantee.

http://217.34.228.137/MAIN/main.htm is an online TOKO catalog - near
identical to the printed catalogue I have. Finding a source in reasonable
quantities is another problem entirely.

However, you may find that toroids are a better bet for multi winding
inductors - see the ARRL handbook for details

Digi-Key carries a large selection of TOKO coils.

Toroids will give you better coils, but they're more expensive in
production.

May I ask why you want the tune the coil?

I think he is looking for something that can be tuned.

Then you use a variable capacitor, or maybe more specificall a trimmer
capacitor.

I haven't priced new coil variable coil forms lately, but I suspect they
may be getting expensive. Toroids are still relatively cheap, and the
cost of trimcaps likely will be cheaper than buying new variable coil
forms.

My idea exactly. Even better: if you replace the trimcap with a
varicap diode, you can make a digitally tuned filter. Very handy for
automated post production calibration.

I offered to help you if you emailed me. I didn't expect to get my
response to your email rejected by your mail bot. It would have been
courteous for you to explain the procedure in your email to me.

Since I can't help you, in fact, there is no point in prolonging the
agony.

John,

I have emailed the address on your website that I found from your last
post - is that not correct?

Also, I don't understand why you email was rejected with no message.
You should have had one from "Marvin" saying to email another address
but to edit the address first (spambots seem to read emails these days
for addresses). My apologies if that didn't happen.

I've set your domain name as allowed so if that is your email address
your mail should get through. Meanwhile I'll test Marvin and see what
is happening.

It is correct.

I didn't say it was 'with no message'. The message required me to do
extra stuff to get a message to you. My point is that you should have
told me about that in advance, instead of it coming as an unpleasant
surprise.

Many people who run a whitelist put that information in their .sig.

Since, as I said, I can't help you with the product you plan to use,
there is no email to send.

My apologies I hadn't thought it was that much work to need warning
about.

On my email client there is the option to resend message - then all
you have to do is paste in the new email address, before you click the
send it button. So on my email client it takes a few seconds. And of
course as it is a whitelist that is only the first time you email.

All of this would not be necessary if only that would bring back
hanging just for spammers :).

It didn't seem as simple as that. Maybe I misread it.
