4.7 µF, 50 V, 500 mOhm ESR — decoupling and bulk storage fit
The TPSD475K050H0500: The 500 mOhm ESR at 100 kHz is the relevant figure for ripple current handling and high-frequency decoupling — a lower ESR means less self-heating and better filtering performance in a DC-DC converter output or a power rail bypass application. This is a standard footprint for tantalum chip capacitors, compatible with common pick-and-place and reflow profiles for a surface-mount assembly line.
The molded construction provides mechanical stability and moisture resistance for general-purpose board-level use.
