Automotive-grade molded tantalum for under-hood power rails
Lifetime and thermal budget at 125 °C
In a typical automotive application where the module sees 105 °C ambient, the capacitor operates with margin, and the lifetime extends beyond the 2000-hour floor.
ESR and ripple current in DC-DC filters
The D case (2917, 7.30 x 4.30 mm footprint) keeps the ESR low enough to avoid excessive self-heating at the ripple currents typical of a 500 mA buck converter.
The TAJ series is a broad automotive-grade portfolio, so a capacitance or voltage variant swap stays within the same footprint and qualification envelope if the exact value is tight.
