Bulk decoupling for 35 V rails — 4.7 µF, 3.1 Ohm ESR
The TAJB475K035HNJ is a molded tantalum capacitor from the TAJ series, offering 4.7 µF capacitance at 35 V with ±10% tolerance. The 3.1 Ohm ESR at 100 kHz determines the ripple current handling and filtering effectiveness on a 35 V supply — lower ESR means less self-heating and better high-frequency decoupling.
Rated for 125°C — 2000-hour endurance, full military temp range
Qualified for 2000 hours at 125°C and a -55 to 125°C operating range, this capacitor suits high-temperature environments such as engine-bay electronics, industrial power supplies, and downhole instrumentation where standard tantalums would derate or fail early.
