Solid Capacitor Motherboards Introduced - Slashdot

The capacitors in question are not tantalum, but solid polymer capacitors. A tantalum capacitor design would be possible, but would be very expensive and also rather bulky. Compared to tantalum capacitors, these capacitors reach much higher capacities at the same physical volume, and the same or better ESL/ESR. See for example here:
