Identification of rare/obsolete parts
 

Dear Friends,

I had currently buy some semiconducors at the ham radio exhibition in
Germany but there are some parts that are unknown to me.
Could you help me to solve that miracle or point me to a link where to
find some information on these parts.

Many thanks in advance for your help.

This maker (and others) do broadband transformers in DIL packages.

Some of these (especially those used in twisted pair/Ethernet) very
commonly show up on the surplus market.

It would be interesting to repurpose them for ham use (e.g. the 88mH
toroids from the NA Bell system in the mid-20th century.)

Tim.

Hi Tim,

thanks for prompt reply.

In this case as it could be a passive device, I will try to
find the pinout by a ohm meter.

Bye
