4.7 µF, 50 V — ESR and temperature profile
The TPSX475M050R0500V: The 500 mOhm ESR at 100 kHz is the figure that governs ripple current handling and power dissipation in the circuit — a lower ESR means less self-heating under AC ripple, which directly affects the 2000-hour lifetime at 85 °C.
Package and footprint — 2917 (7343 Metric)
The surface-mount footprint matches the industry-standard tantalum layout for this case size — no board-spin required if your existing 2917 pad pattern already accounts for the 0.059-inch max height.
