The TPSD477K006H0200: Maximum ESR is 200 mOhm at 100 kHz, which sets the ripple current capability and the filtering corner frequency for the output stage of a switching regulator.
Maximum ESR is 200 mOhm at 100 kHz — this value determines the ripple current the capacitor can handle and the filtering performance at the switching frequency of a DC-DC converter.
