330 µF at 10 V — bulk decoupling anchor
The TPSD337K010H0100: This combination makes it a natural fit for bulk decoupling on power rails or energy storage in hold-up circuits where board space is tight.
ESR and temperature — the real derating drivers
With 100 mOhm ESR, this part handles ripple current without excessive self-heating — the ESR figure is the one that governs AC ripple capability, not the capacitance alone. The -55°C to 125°C operating range covers industrial and automotive underhood environments, but note that tantalum capacitors require voltage derating above 85°C; a 50% derating at 125°C is standard practice to avoid field failures. The ±10% tolerance is typical for tantalum electrolytics and leaves enough margin for most filtering and decoupling applications — just account for the temperature coefficient when sizing the rail.
