This TAJA475K010H is a molded tantalum capacitor from the TAJ series, delivering 4.7 µF capacitance at 10 V with a 5 Ohm ESR. The 1206 (3216 Metric) case fits standard PCB land patterns for bulk decoupling on power rails, local filtering near ICs, or hold-up storage in low-voltage circuits.
KYOCERA AVX lists the TAJA475K010H as Active.
ESR and temperature — the real-world limits
The 125°C rating provides margin, but the ESR limits the allowable ripple before internal temperature rise shrinks the lifetime. The molded case (Type: Molded) provides mechanical protection and standard reflow solder profile compatibility. No conformal coating issues — the epoxy body resists common solvents used in post-solder cleaning.
