Molded tantalum for harsh-environment power rails
The TAJA225M006RNJ is a molded tantalum capacitor from the TAJ series, rated at 2.2 µF with a 6.3 V working voltage and ±20% tolerance. Its 9 Ohm ESR makes it a practical choice for bulk decoupling on low-voltage supply rails where ripple current is modest. That means this part holds its capacitance and leakage characteristics across the thermal extremes found in engine-bay electronics, satellite power distribution, or downhole instrumentation — environments where a commercial-grade electrolytic would dry out or crack.
1206 footprint and board-fit notes
Housed in a 1206 (3216 Metric) case, the TAJA225M006RNJ measures 3.20 mm x 1.60 mm with a seated height of 1.80 mm max. The molded body suits standard reflow profiles, and the manufacturer size code A confirms the low-profile variant — useful when board height is constrained under a mezzanine or enclosure lid.
