Values given on the table are minimum requirements unless otherwise specified. When selecting capacitors,

tolerance and temperature coefficient must be considered to make sure that the requirement is met in all

potential operating conditions.

1RWH : Polarized capacitor should never be used, since the capacitor voltage can reverse during operation.
