Automotive-grade molded tantalum for power rail decoupling
The TAJB476M010TNJ is a 47 µF molded tantalum capacitor from the TAJ series, rated 10 V with ±20% tolerance.
ESR and endurance at temperature
ESR is specified at 1 Ohm at 100 kHz (cite:) — this sets the ripple current ceiling for bulk decoupling on a 10 V rail. The 2000-hour endurance at 125°C (cite:) means the capacitor holds its capacitance and ESR within spec over the typical automotive module lifetime, even in continuous high-temp operation.
