Bulk decoupling with a 200 mOhm ESR ceiling
The ±20% tolerance is standard for tantalum electrolytics; the actual capacitance at the operating voltage will be close to the nominal value because tantalum capacitors do not exhibit the DC bias derating that MLCCs do. This makes the TPSV476M035R0200 a predictable choice for timing circuits or hold-up capacitors where the capacitance must stay stable across the applied voltage range.
Temperature range and board-fit
The manufacturer size code V maps to a standard pad layout for the 2924 case; the same footprint is shared across the TPS series, so a BOM change to a different capacitance or voltage rating within the series does not require a board spin.
