Bulk decoupling on a 24 V rail — what the ratings mean
The TPSD106M035R0125: The 10 µF capacitance at 35 V rated voltage puts this part squarely in the 24 V intermediate-bus decoupling role — the 35 V rating provides 46 % headroom above a nominal 24 V rail, enough to absorb load-dump transients without exceeding the derating guideline of 50 % of rated voltage for tantalum capacitors. 125 mOhm ESR keeps the ripple current self-heating manageable: at 1 A ripple the internal temperature rise stays under 15°C, which matters when the capacitor shares a board with a switching regulator running at several hundred kilohertz. The ±20 % tolerance is the standard for tantalum electrolytics — the actual capacitance at the 35 V bias will be at the low end of the range due to DC voltage derating, so budget 8 µF effective for a 10 µF nominal part at full rated voltage.
