Molded tantalum, 0.68 µF at 50 V, 7.9 Ohm ESR
The TAJA684K050RNJ is a surface-mount molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 0.68 µF at 50 V with ±10% tolerance. The molded construction gives mechanical robustness against vibration and thermal cycling in those environments.
1206 footprint, tape-and-reel delivery
The 1206 (3216 Metric) footprint — 3.20 mm x 1.60 mm body, 1.80 mm seated height — is a standard size that matches common PCB land patterns without layout adjustment.
