Bulk decoupling for 48 V and intermediate rails
The TAJE156K050BNJ: At 15 µF and 50 V, this TAJ series molded tantalum capacitor sits in the sweet spot for bulk decoupling on a 48 V bus or as the output filter on a 12 V-to-3.3 V intermediate rail.
Temperature range and lifetime budget
The 2000-hour lifetime at 125°C is the hard ceiling: every 10°C drop roughly doubles the life, so at 85°C the expected life extends well beyond 8000 hours.
Active production — no redesign pressure
2917 (7343 Metric) case, size code E — 7.30 mm x 4.30 mm footprint, 4.30 mm seated height. The molded case is polarity-sensitive; the anode band marks the positive terminal. Standard reflow profile applies.
