TAJB684M050RNJ is a 0.68 µF molded tantalum capacitor rated at 50 V, ±20% tolerance. That voltage margin covers 12 V, 24 V, and 48 V rails with healthy derating — a 50 V part on a 12 V bus gives 4× headroom against surge and ripple.
In a low-impedance rail, the ESR dominates the AC loss — a 100 kHz ripple of 100 mA dissipates 80 mW, which the molded case must sink without exceeding the 125 °C limit.
0.68 µF at 50 V, ±20% tolerance.
The part is listed as General Purpose in the TAJ series. KYOCERA AVX tantalum capacitors in this series are typically RoHS compliant, but confirm the specific lot certificate at RFQ.
