The TPSD337M004R0045: The 45 mOhm ESR is the figure that governs ripple current handling and self-heating in a bulk decoupling or hold-up capacitor role — lower ESR means less power dissipated as heat for the same ripple current, which directly affects reliability in a tight thermal budget.
The 45 mOhm ESR at 100 kHz is the standard reference point for tantalum capacitors in this case size.
The ESR is 45 mOhm. For a bulk tantalum capacitor in a 2917 case, this ESR determines the ripple current rating — lower ESR means the capacitor can handle more AC ripple without exceeding its internal temperature rise limit. It is the primary selection parameter after capacitance and voltage for power rail decoupling.
