Tantalum is just another type of  electrolytic capacitor, it uses different
material. Most electrolytic capacitors use aluminum. The difference is
tantalum in place of aluminum.  The higher the voltage the better off you
will be also. Go with the 35Vdc rating. This will handle any transient
spikes. Also because of the various temperatures located there, there will
also be variations in the capacitance.
