47 µF, 1.6 Ohm ESR in a 1206 case
The TAJA476K006RNJ is a 47 µF molded tantalum capacitor rated at 6.3 V in the compact 1206 (3216 Metric) case, part of the KYOCERA AVX TAJ series. The 1.6 Ohm ESR sets a floor on ripple current handling — at 47 µF and 6.3 V, this part suits bulk decoupling on a 3.3 V or 1.8 V rail where the ripple current stays under ~400 mA RMS. The 1206 footprint keeps the board area to 3.20 mm x 1.60 mm, fitting dense layouts on multilayer PCBs.
That means it holds its capacitance and leakage within spec across avionics cold-soak, outdoor telecom enclosures, and downhole tool environments — no need to qualify a separate high-temp variant for the same BOM.
