Toko Coil part numbers

[zeitghost]

Does anyone know the rhyme or reason behind Toko part numbers?

I've got some that I bought, so I know what they are, but the numbers on them don't seem to correspond to the parts catalogue...

For instance, I have 90D0-162-002-86023, which I didn't buy.

How do I figure out what that is?

I've got a drawer in the stores full of this type of thing & it must be good for something or other...

Try looking for the last three groups the first group could be just a date code...??

I just stumbled across a Toko catalog from 1995 and it isn't in there so it isn't that old. Even having the catalog in front of me it is hard to find rhyme or reason. Here is what I can pull out of the part numbers. '#' means a numeric digit and '...' means there is much more to the number after the suffix shown:

Dielctric filters - #DF...

Variable coils #C...

Fixed Inductors (SMD) - LL..., ##c..., #c..., ##R, #DF (wait, wasn't that a filter?!?)

variable coils - #P..., #K...

Molded coils - MC###

Bias oscillating coils - no clue on these

Fixed inductors (not SMD?) - 8R..., 10R...

AM tuning coils - FB...

LC filters (SMD) - FS..., 4F...

LC filters (not SMD?) - 5V..., many other families with no similarity

Helical filters - #CH..., #HRW..., CB..., HR...

Balun transformers - B#...

Ceramic filters and oscillators - ECF..., CF..., C...

I hope that helps.

Thanks for that; I can make no sense of any of it really.

The coils are 7mm types in cans, and that's about as far as it goes... )

Ho hum.

What's even weirder, I can't match the numbers on coils I ordered myself tothe toko numbers in the ancient catalogue I've got...

Sounds like the contents of the drawer are prime candidates for the electronic disposals bin (under WEE).

This says a lot really...

In other words, toss the lot in the bin & forget about it... )
