I'm using a max 232 from maxim, it need 10uF polarized capacitors, is any problem to use tantalio capacitors? or I need to use electrolitic capacitors.
Yes .. you could a tantalum or tantalium cap
i only used those . and had big runs of boards never had problems
I think most people use tatalium caps with those chips . because they are small .
No my friend look at the maxim datasheet for all 232 drivers
nominal cap should be 1.0uF but you could even use 0.1uF
10uf is too much .. it will work of course ,, is a matter of price here !
You could use 1000uF but the little power supplys only will output 25mA at most . So is a matter of if you use those power supply to power something .i have used the negative source to power LCDs .and even 1uF was ok ! Most people just use the chip for the rs232 deal .. but you should also know that there are two power supplys capable of putting out 25mA.
wich is not bad ..
I've actually used 1uf non-polarized ceramic surface mount caps without issue on the TI max232 chip. It's cheap, and I needed small footprint surface mount components.
