6.8 µF at 16 V — what it buys the board
The TAJA685K016H: 6.8 µF capacitance with 16 V rated voltage — the standard 80 % derating guideline keeps this cap below 12.8 V in service, giving margin against rail transients. ESR is 3.5 Ohm typical. That is on the higher side versus polymer or MLCC alternatives — expect a higher ripple voltage on the output if used as a bulk cap after a regulator. For filter or timing roles where ESR is less critical, it still fits cleanly.
Package and footprint — 1206 case, size code A
1206 (3216 Metric) case, size code A per the TAJ series. Footprint is 3.20 mm x 1.60 mm, seated height 1.80 mm max. Standard reflow profile for tantalum — no special pad geometry beyond the datasheet recommendation. Supplied on Tape & Reel (TR) — pick-and-place ready. No special MSL handling beyond the typical tantalum level 3 if molded; confirm with the lot-specific reel label.
The TAJ series is a broad-production line from KYOCERA AVX, so supply continuity is stable. Available through independent distribution. No stock-holding claim; sourced per RFQ.
