68 µF, 20 V, 200 mOhm — bulk decoupling for power rails
The TPSE686K020R0200: The ±10% tolerance on the 68 µF value means you can count on at least 61.2 µF minimum, which is enough margin for most regulator loop stability requirements.
Temperature range and operating envelope
At the hot end, the DC bias derating applies — a 20 V-rated tantalum should not see more than about 13-14 V steady-state at 125°C to stay inside the safe operating area; the manufacturer's derating guideline is typically 50% of rated voltage above 85°C. The molded construction gives it better mechanical robustness than a conformal-coated chip — the epoxy body resists cracking during reflow and handling, which matters when the board sees thermal cycling or vibration in a motor-drive or power-supply application.
