AW: [En-Nut-Discussion] RS232 Driver (ST202), are the caps polarised on non-polarised???

[Robert Hildebrand]

Hi Douglas,

the SMD-Caps for the RS232 driver are not polarised. Only the capacity is
important for the function. As higher capacities (e.g. 10µF used be the
MAX232) are only available as polarised elko or tanral caps you find in most
schematics the symbols for polarised caps.

Hi People,

I was checking out the Rev D board, and I noticed the SMD caps (100n) looked
the same as all the non-polarised 100n caps on the board.

Looking at the EAGLE file, it appears they are non-polarised.

Checking out the ST202 data sheet they should be polarised.

Are they actually polarised or not???

Cheers Douglas
