The tantalum polymer SMD are solid-state capacitors that demonstrate no wear out mechanism when operated within their recommended guidelines. Unlike their MnO2 counterparts, polymer capacitors don’t need to be derated as aggressively. Under most conditions of consumer electronics devices, polymer capacitors only need about 10% derating.
