TAJE476M020RNJ is a 47 µF, 20 V molded tantalum capacitor from the KYOCERA AVX TAJ series, in the standard E case size (2917 / 7343 metric). The 20 V rating provides a comfortable derating margin for bulk decoupling or hold-up capacitance in a power supply.
900 mOhm ESR — ripple current and self-heating budget
The 900 mOhm ESR sets the ripple-current ceiling: self-heating limits the usable AC current before the 125°C rating is reached.
TAJE476M020RNJ carries an Active product status from KYOCERA AVX.
