4.7 µF, 16 V, 3.5 Ohm ESR — TAJ series molded tantalum
The TAJB475M016HNJ is a molded tantalum capacitor from the TAJ series, rated at 4.7 µF with ±20% tolerance and a 16 V DC working voltage. The 3.5 Ohm ESR at 100 kHz sets the ripple current ceiling and self-heating budget for this size code B package. Operating from -55°C to 125°C with a 2000-hour endurance rating at the upper limit, this part fits into high-temperature environments such as engine-bay electronics, industrial motor drives, and avionics power supplies where the ambient exceeds standard commercial grades.
