The 0805 (2012 metric) case keeps the footprint small — 2.05 mm x 1.30 mm — which fits tight board layouts in portable or space-constrained designs. The 4 Ohm ESR is a practical number for this case size: it limits ripple current to about 300 mA RMS at 85°C, which is enough for decoupling a 3.3 V rail or smoothing a low-power DC-DC output.
The molded construction and general-purpose rating make it a straightforward drop-in for bulk decoupling or timing circuits.
RoHS compliance is standard for the TAJ series from KYOCERA AVX; the part number suffix does not indicate a non-RoHS variant.
Yes — the 0805 case, 15 µF, 4 V rating, and ±20% tolerance match many general-purpose tantalum parts from other series. Confirm the ESR (4 Ohm) and temperature range (-55 to 125°C) are acceptable for your circuit; the molded package is a direct footprint swap.
