Capacitance and voltage rating — BOM-fit check
The TAJA475K020TNJ: This part is a 4.7 µF tantalum capacitor rated at 20 V DC, from KYOCERA AVX's TAJ series. The capacitance and voltage are the primary selection parameters for decoupling, filtering, or hold-up applications — confirm these match your rail voltage with margin (typically 80 % derating for solid tantalum).
Packaging and assembly suitability
Production continues, so the part can be sourced through standard independent distribution channels.
