Bulk decap for low-voltage rails
The TAJD108M002RNJ: 1000 µF at 2.5 V with 200 mOhm ESR — this is a bulk tantalum for holding up a low-voltage rail during load transients. The 200 mOhm ESR limits ripple current before self-heating becomes a concern; for a switching regulator output, pair it with a low-ESR ceramic to shunt the high-frequency ripple. No derating needed across the band — the molded case handles the mechanical stress.
