Rated 1 µF at 20 V, the TPSA105K020R3000 gives 60 % derating margin on a 12 V supply — a solid fit for a decoupling or timing cap where the rail is clean and the ripple stays under a few hundred mV. The 3 Ohm ESR sets the ripple current ceiling: at 100 kHz, the self-heating from 100 mA ripple is about 30 mW, well within the 125 °C rating. For a bulk-cap role with higher ripple, a lower-ESR part in the same case size would be a better call.
