Molded tantalum, 0.68 µF at 50 V — TAJ series fit
The TAJC684K050SNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 0.68 µF with ±10% tolerance and a 50 V working voltage. The 7 Ohm ESR at 25°C sets the ripple current ceiling — for a 100 kHz switching supply output, the self-heating from ripple current stays manageable below 150 mA RMS. The 2312 (6032 Metric) case fits standard reflow profiles; the molded construction provides mechanical stability across the full -55°C to 125°C range.
