The TPSD685K050R0300: 300 mOhm ESR governs the ripple current handling and self-heating; for a given ripple current, the I²R loss is fixed by this value, so the capacitor's temperature rise is predictable from the load profile.
The ±10% tolerance is standard for tantalum electrolytics and sufficient for bulk decoupling, hold-up, and filter applications where the exact capacitance value is not critical.
The equivalent series resistance is 300 mOhm, which determines the ripple current rating and self-heating under load.
