Active production — 1 µF molded tantalum for wide-temp designs
11 Ohm ESR — the ripple-current ceiling
Equivalent series resistance is 11 Ohm, which limits the ripple current the capacitor can handle before self-heating becomes a concern. For a 1 µF part, this ESR is on the high side — the capacitor is better suited for bulk storage or timing circuits than high-frequency decoupling on a power rail.
1206 footprint — board-layout fit
Housed in a 1206 (3216 Metric) case, 3.20 mm x 1.60 mm, seated height 1.80 mm max, the part fits standard reflow processes for surface-mount assembly. Manufacturer size code A indicates the smallest case in the TAJ series, saving board space but also carrying the highest ESR per capacitance.
