This TAJD475K050RNJ is a 4.7 µF molded tantalum capacitor rated at 50 V, ±10% tolerance. The 50 V rating provides headroom for a 12 V or 24 V rail — the derating rule of thumb (50% of rated voltage) keeps the applied voltage at or below 25 V, which is standard practice for tantalum reliability.
The molded construction handles thermal cycling without cracking the dielectric — a known failure mode in uncoated tantalum chips.
Housed in the 2917 (7343 Metric) case, size code D, with dimensions 7.30 mm x 4.30 mm and a seated height of 3.10 mm max. The 1.4 Ohm ESR is the figure to check for ripple current handling — a higher ESR means more self-heating, so confirm the ripple current in your circuit stays within the capacitor's dissipation limit.
