Bulk decoupling with known ESR
The TAJB476K010H: At 47 µF and 10 V with a 1 Ohm ESR, this TAJ-series molded tantalum handles bulk bypass on 3.3 V or 5 V rails where the ESR damps resonance with the board's parasitic inductance — the 1 Ohm floor limits ripple attenuation but prevents the ringing that a lower-ESR ceramic might excite.
