Ceramic, tantalum, polyester SMD capacitors if left unused for a long time will present the same problems as aluminum electrolytic capacitors directly affecting their durability and high current leakage, loss of capacitance, depolarization etc? are they also unstable to long term storage?

Tantalums can sometimes give issues but this is more related to the old 'bead' (through hole) type - can be 'little fire makers' in the right (wrong) situation!

Hello,

The capsite will give you a lot of information on capacitors:
There are two pages on reliability.
