330 µF bulk decoupling for low-voltage rails
The TPSE337M006S0100V: The 100 mOhm ESR at 100 kHz keeps ripple heating under control and gives the capacitor a clean frequency response for filtering switching-regulator output noise. In a buck converter output stage, that ESR figure sets the output ripple amplitude and the capacitor's own self-heating from ripple current.
Temperature rating and lifetime budget
Rated for -55°C to 125°C operation with 2000 hours endurance at the top temperature. For ambient temperatures below 85°C, the expected life extends well beyond the 2000-hour figure. It fits the common 2917 land pattern used across the industry, so a PCB already laid out for a 7343-31 or 7343-20 case will accept this part with no pad change.
