4.7 µF, 20 V — derating for 12 V rails
The TPSB475K020R0750: At 4.7 µF and 20 V rated voltage, this molded tantalum capacitor gives a 60 % derating margin on a 12 V rail — standard practice for tantalum to avoid surge failures. The ±10 % tolerance keeps the actual capacitance within 4.23 µF to 5.17 µF across the reel. Higher ESR than polymer types, but the molded construction gives a predictable failure mode — open circuit, not short.
The 1411 (3528 Metric) case, size code B, measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm — a common footprint that matches many standard tantalum layouts.
