Product details

0.68 µF, 16 V, 1206 — molded tantalum for tight board spots

The TAJS684M016RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated 0.68 µF at 16 V with ±20% tolerance. The 1206 (3216 Metric) case fits standard pick-and-place and reflow profiles — no hand-solder rework needed for production volumes. The 25-ohm ESR at 100 kHz sets a ripple-current ceiling: this cap is suited for DC-blocking, coupling, and low-frequency bypass, not for high-ripple bulk decoupling on a switching regulator output. For that role, a lower-ESR tantalum or MLCC would be the better fit.

Lifetime is specified at 2000 hours at 125°C — this is the accelerated endurance test condition. At lower temperatures the expected life extends significantly; derate the applied voltage and ripple current to stay within the reliability target for the mission profile.
