arhi is just really nicearhi is just really nicearhi is just really nice
Default 87sm/twn
Anyone have idea what this is?

square SOT block 3 pins on one and 3 pins on other side (6 pins total)
first line: 87SM
second line: TWN

thanks in advance

It might be this (attached) but I have no idea what it actually does (found the datasheet here: http://www.alldatasheet.co.kr/datash.../23Z106SM.html )

If there is a good sole that can explain what the heck this part does

thanks in advance

hi,
The are 'inline' interference suppressors, for two and three core cables.
They are wound is such a 'sense' as any common mode interference is attenuated.

I understand how 126 works (3 separate 2line interference suppressors) but the 3line is evading me ... can you give me a simple 3 line example schematic with some base explanation ..

the way I understood it, 2line one can be, for example, placed on power line so the inside of the circuit will be isolated from the interferences that exist on the main power input... but .. 3line .. damn, I have no idea and the "symbol" for the 3line one does not tell me much
