I'm a newbie in these waters so please bear with me and my potentially dumb question.

I have a schematic of a device I want to build that I'm trying to decipher and source the parts for. In the parts list, aside from usual things and codes that are easily google-able and easy to find, I have also the entry "TRICOIL". I've tried google and some forums but no luck. Does anyone know what this part is and what it's called in the language of electronics retailers? I attach a snapshot of the schematic for easier understanding.

Thanks in advance and cheers!

    \$\begingroup\$ What is it doing in the circuit? Would a transformer with two secondaries connected in series make sense? \$\endgroup\$ – evildemonic Mar 25 '20 at 17:00

    \$\begingroup\$ i agree with @evildemonic .... google transformer multiple secondaries .... can you post the whole schematic? (or a link) \$\endgroup\$ – jsotola Mar 25 '20 at 17:08

    \$\begingroup\$ Can you post a larger section of the circuit or link to the whole thing? It would also help to know what the circuit is. \$\endgroup\$ – JRE Mar 25 '20 at 17:10

    \$\begingroup\$ @MarkoBarovic please either delete this question, or better, yet, post an answer yourself, explaining what this is! \$\endgroup\$ – Marcus Müller Mar 25 '20 at 18:39

    \$\begingroup\$ @evildemonic, a series-connected secondary is nothing more than a center-tapped secondary. (The right-most downward pointing wire is the center tap, in this case.) The figure just looks strange because the transformer windings are conflagurated (that's a tech term /s) to fit within the part's square shape and case pin positions on the schematic diagram. My guess is "TRICOIL" is a brand name or something. \$\endgroup\$ – Jim Fischer Mar 25 '20 at 18:49

Ok, so I got an answer from further reading and other sources. This was a "custom" name for a trifilar wound toroid acting as a transformer in several parts of a RF transciever device.

Thanks all for the insight and helpful comments!

    \$\begingroup\$ Wilco! It has a time limit after which I can accept it since it's my own. In any case I didn't know that was supposed to be done so thanks a lot mate! Love this community! \$\endgroup\$ – MarkoBarovic Mar 27 '20 at 13:23
