22 µF, 2.5 V — what this tantalum cap does on your board
The TAJR226K002RNJ: This is a molded tantalum capacitor from the TAJ series, rated 22 µF at 2.5 V with ±10% tolerance. The 0805 case (2.05 mm x 1.30 mm footprint) is a common surface-mount size that reflows cleanly under standard profiles — no special pad geometry needed. For a 2.5 V rail, that covers most decoupling duties on a mixed-signal board.
Package and rework — 0805 is a hot-air friend
0805 case, size code R. The molded body is 1.20 mm seated height max. No exposed metal on top — orientation is marked by the polarity band on the positive end. Standard reflow profile for tantalum: peak 260°C, ramp rate ≤3°C/s.
