The TPSV157M020R0080: The 80 mOhm ESR keeps ripple heating manageable in a power-supply bypass role — a 1 A ripple current through 80 mOhm dissipates 80 mW, well within the package's thermal budget at 125 °C ambient. The 20 V rating leaves headroom on a 12 V rail (derated to 80 % of rated voltage per tantalum best practice) and still covers a 5 V rail with margin for transients. The 150 µF value suits bulk decoupling for a moderate-current regulator output or a point-of-load filter.
2924 case, size code V — board footprint and height
The manufacturer size code V tells the layout engineer the land pattern and pad geometry to use — the 2924 case requires a solder pad that matches the terminal width and a keep-out zone for the molded body. The molded case provides mechanical stability during reflow and resists cracking from board flex — a known failure mode for uncoated tantalum chips. No special handling beyond standard MSL precautions.
