I am currently modifying and developing based on arduino ethernet board to interface with a relay and fpc connector.http://arduino.cc/en/Main/ArduinoBoardEthernet
I would like to ask regarding this component :
5 10u CPOL-EUSMCB SMC_B C8, C11, C13, C18, C19 POLARIZED CAPACITOR, European symbol
I realized these are the decoupling capacitors for the arduino ethernet board.
However, based on my observation these capacitors on the original board are non-polarized capacitors.
May i know should i be using a polarized one or non-polarized capacitor in this part?
