As I recall, both are comparable in energy density, and I would prefer to avoid tantalum for the cost, potential failure mode, weight, and use of conflict minerals. In any case, check ripple current in the datasheet, or calculate dissipation from ESR and ripple current (and then use RthJA or estimate it from package size, materials and similar parts). | |
