[sdiy] SMD capacitors : choosing dielectric type

[jays at aracnet.com]

Frédéric,

I don't know which caps you are looking at or how you plan on soldering
them.

But one issue with plastic SMD caps is they can be very temperature
sensitive. There are some that you can melt quite easily soldering with
a soldering iron. So check your specs about soldering them before you
buy.

Good luck!
