What this cap does on a board
The TPSD227K010R0100: This is a 220 µF molded tantalum capacitor rated at 10 V with a 100 mOhm ESR — a common bulk decoupling choice for 3.3 V and 5 V power rails in industrial and telecom gear. The ±10% tolerance keeps the effective capacitance above 200 µF at the rated voltage, which matters when you are sizing hold-up capacitance for a microcontroller or FPGA rail. The 100 mOhm ESR is the figure that sets ripple current handling and transient response.
No derating exception needed for cold start or hot soak.
