4.7 µF, 25 V molded tantalum — B-size case, 1.5 Ohm ESR
The TPSB475M025Y1500 is a 4.7 µF ±20% molded tantalum capacitor rated at 25 V, in the B-size 1411 (3528 Metric) case. The 1.5 Ohm ESR sets the ripple current ceiling — at 25 V and 4.7 µF, the self-heating from ripple current is the limiting factor, not the voltage rating.
B-size 1411 footprint — board layout fit
The B-size case measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 1411 (3528 Metric) footprint is standard for this density.
