The TAJP475M016RNJ: 4.7 µF capacitance with ±20% tolerance and a 16 V rated voltage gives you a solid decoupling cap for a 3.3 V or 5 V rail, with enough headroom to stay within derating guidelines. The 5 ohm ESR is typical for a small-case tantalum at this value; it limits ripple current handling and contributes to self-heating, so it is best suited for bulk decoupling rather than high-ripple switching supply outputs.
0805 case and temperature range – board fit and environment
Housed in an 0805 (2012 metric) molded case, this part fits a compact footprint (2.05 mm x 1.35 mm) with a seated height of 1.50 mm – typical for dense PCB layouts.
