Bulk cap for a 10 V rail — 100 µF with 1.4 Ohm ESR
The TAJB107M010ANJ: This is a molded tantalum capacitor in the TAJ series, rated 100 µF at 10 V with a maximum ESR of 1.4 Ohm at 100 kHz.
125°C endurance — 2000 hours at the ceiling
That 125°C ceiling matches the under-hood automotive ambient or a tightly packed industrial enclosure where the local air temperature near the power supply hits 105°C. The 2000-hour endurance at 125°C means the cap survives continuous operation at that temperature for about 83 days — adequate for a product with a 5-year life if the hot time is a fraction of the duty cycle.
Availability is confirmed at RFQ against the required quantity.
