The TAJB155M025RNJ: 1.5 µF at 25 V with ±20% tolerance. The 5 Ohm ESR is typical for a B-case tantalum at this capacitance and voltage — higher than a ceramic or polymer cap, so ripple current generates more self-heating. Derate the voltage by 50% on low-impedance rails to stay inside the safe operating area.
The 1411 (3528 Metric) molded case, size code B, measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm. Surface-mount reflow profile follows standard tantalum recommendations: preheat ramp rate under 3°C/s, peak temperature 260°C, time above 217°C kept under 30 seconds.
