The TPME477K010R0023: This is a 470 µF, 10 V rated molded tantalum capacitor in the TPM series from KYOCERA AVX. The 23 mOhm equivalent series resistance is low enough that ripple current from a switching regulator won't drive excessive self-heating — a key consideration when the cap sits on the output of a buck converter handling several amps.
The molded case construction handles the thermal cycling without the cracking risk seen in some conformally coated tantalums.
The 7.30 mm x 4.30 mm footprint and 4.30 mm seated height match the industry-standard tantalum outline — board layouts already using a 7343 cap can drop this in without a pad revision.
