Product details

6.8 µF at 10 V — AEC-Q200 molded tantalum for automotive BOMs

The TAJA685K010TNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor, 6.8 µF ±10% tolerance, rated 10 V DC, in a 1206 (3216 Metric) surface-mount case. That ESR limits the AC ripple current to roughly 200-300 mA before self-heating becomes a concern — fine for decoupling a 3.3 V rail or filtering a low-power DC-DC output, but not for high-ripple power stages without derating.

1206 case — board-fit and temperature range

The 1206 (3216 Metric) footprint is a common size for automotive and industrial PCBs.

Frequently asked questions

Can TAJA685K010TNJ replace TAJA685K010RNJ?

Both are KYOCERA AVX TAJ series parts with the same capacitance, voltage, tolerance, and case size. The suffix difference (TNJ vs RNJ) typically indicates packaging or termination finish variation — check the specific datasheet termination details, but electrically they are interchangeable on the same BOM position.
