The TPSE477K010R0045: That ESR figure is the key number for a repair bench: it tells you the ripple current the part can handle before self-heating becomes a problem.
Surface-mount package suits standard reflow profiles; no special handling beyond typical MSL precautions.
The ESR is 45 mOhm. That is low for a 470 µF tantalum, meaning it can handle higher ripple current without excessive self-heating — useful for decoupling a switching regulator output where ripple current can reach several hundred mA.
