The TAJA155K035TNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 1.5 µF ±10% with a 35 V working voltage. The molded construction provides consistent dimensional tolerance and moisture resistance compared to conformal-coated tantalums.
ESR and ripple current — what the 7.5 Ohm spec means for your circuit
The 35 V rated voltage provides a 1.4× derating margin against a typical 24 V automotive bus (nominal 28 V max during charging). This is standard practice for tantalum capacitors to avoid surge failures — the manufacturer recommends derating to 50-60% of rated voltage for DC bias.
