The TPSE686M025R0200: The 200 mOhm ESR limits the self-heating under ripple — for a 1 A pk-pk ripple at 100 kHz, the internal temperature rise stays under 5°C at 25°C ambient, within the safe operating area.
Derating to 50% of rated voltage (12.5 V) is standard practice for tantalum capacitors to avoid surge failures; at 12.5 V the capacitance recovers closer to the nominal value.

The ESR is 200 mOhm. This value determines the self-heating under ripple current — a lower ESR means less internal temperature rise for the same ripple, which directly affects the capacitor's lifetime in a power-supply output filter.
