TAJC685K050ANJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 6.8 µF at 50 V with ±10% tolerance. The 2312 (6032 Metric) case — size code C — measures 6.00 mm x 3.20 mm x 2.80 mm seated height, surface-mount, on tape and reel.
Rework and board-fit notes for the bench
Molded tantalum case, no exposed metal on the top — the hot-air nozzle sits directly on the epoxy body. The 2312 footprint is large enough for hand soldering with a chisel tip; orientation is marked by the polarity stripe on the top face. Will it survive the hot air? Yes — the molded body handles 260°C peak reflow without cracking, provided the part is dry (bake at 125°C for 24 hours if the seal is compromised).
