The TAJT225M025RNJ: This is a molded tantalum capacitor from the TAJ series, 2.2 µF at 25 V with ±20% tolerance. The 4.5 Ohm ESR is on the higher side — expect more self-heating than a low-ESR polymer part, so derate for ripple current in power rail decoupling. The 1411 (3528 Metric) case is a common footprint; the T size code matches the 3.50 x 2.80 mm body and 1.20 mm seated height.
Rework and mounting notes for the bench
Surface-mount 1411 case, molded body. The part is MSL 1 per the TAJ series — no bake-out needed before reflow. The polarity band is marked on the top — confirm orientation before placement. A 0.50 mm pitch rework tip at 300 °C, 30 seconds per side, is enough to float the part off without cooking the adjacent passives.
