470 µF at 10 V — derating margin and bulk decoupling fit
The TPSE477M010R0050: The 50 mΩ ESR is the spec that governs ripple current handling and self-heating — at this impedance the capacitor can absorb the ripple from a switching regulator output without exceeding its internal temperature rise limit.
2917 case, size code E — PCB footprint and reflow profile
Surface-mount molded body handles standard reflow profiles (260 °C peak) without the moisture-sensitivity bake that some larger-case tantalums require — check the MSL on the reel label, but the molded construction typically runs MSL 1.
