Bulk decoupling for a 20 V rail — 47 µF with 75 mOhm ESR
The TPSD476M020R0075: That ESR figure is the key parameter for ripple handling: at 100 kHz switching frequency, the capacitor's self-heating stays manageable in a bulk decoupling role on a 20 V rail.
Temperature range and lifecycle status
The TPS series is a general-purpose MnO2 tantalum line, not a low-ESR polymer type — the 75 mOhm ESR is competitive for a 47 µF / 20 V part in this package.
