1 µF, 16 V, 20 Ohm ESR — the limiting spec
The TAJR105M016RNJ: This is a 1 µF molded tantalum capacitor in the 0805 case, rated 16 V, with a 20 Ohm ESR. The ESR is the spec that governs ripple current handling and transient response — at 20 Ohm, this part is suited for decoupling and filtering where the impedance budget is generous, not for high-ripple bulk storage.
Temperature range and board fit
The 0805 (2012 metric) footprint is a standard two-terminal chip — no special pad geometry needed beyond the usual 0.50 mm overlap per terminal. The height seated at 1.20 mm max keeps it under low-profile components.
