The TPSD337M006R0070V: The 70 mOhm ESR at 100 kHz is the figure that governs ripple-current handling and output filtering — at this resistance, the capacitor dissipates I²R heat internally, and the self-heating limits the usable ripple to what the 125°C-rated body can shed without exceeding the 2000-hour lifetime at that temperature.
The ESR is 70 mOhm at 100 kHz. This value sets the self-heating under ripple current — a lower ESR means the capacitor runs cooler and delivers longer life at a given ripple level. For a 330 µF output cap on a 6.3 V rail, the 70 mOhm ESR is a mid-range figure; it handles typical switching-regulator ripple without excessive heating.
Rated for -55°C to 125°C operating range, with a 2000-hour lifetime at the 125°C endpoint. The full military-temperature band means it suits outdoor telecom, industrial control, and automotive under-hood environments where the ambient cycles through -40°C to 105°C.
