The TAJR155M010RNJ: This is a 1.5 µF, 10 V rated molded tantalum capacitor from the KYOCERA AVX TAJ series, in an 0805 (2012 Metric) surface-mount package. The ±20% tolerance is standard for tantalum — expect the actual capacitance to land between 1.2 and 1.8 µF at 25 °C. With a 20 Ohm ESR, this part is suited for decoupling, bypass, and timing roles where moderate series resistance is acceptable, rather than low-ESR power rail filtering.
The 0805 case (2.05 mm x 1.30 mm footprint, 1.20 mm max seated height) keeps a low profile on the board, useful under mezzanine cards or in tight enclosures.
