TAJA686K004RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 68 µF at 4 V with ±10% tolerance. The 1.5 Ohm ESR is typical for a 68 µF tantalum in this case size — it sets the ripple current ceiling and the output impedance on a supply rail. For a 3.3 V rail decoupling 68 µF at 4 V gives 20 % voltage margin, which is comfortable for most ASIC and FPGA core supplies.
