It carries AEC-Q200 qualification — the automotive passive-component stress test — which means it has passed temperature cycling, moisture resistance, and vibration prequalification required for OEM PPAP submissions. ## 1206 footprint, ESR, and layout fit The manufacturer size code A confirms the 3.20 mm × 1.60 mm land pattern — a direct drop-in for any 1206 tantalum footprint on the board. ESR is specified at 2.4 Ohm — this is the series resistance that governs ripple current handling and output voltage ripple in DC-DC converter input/output filters. For a 6.8 µF cap at 20 V, the 2.4 Ohm ESR is typical for a small-case tantalum; if lower ripple is needed, a larger case size or polymer alternative should be evaluated.","metaTitle":"TAJA685K020TNJ – KYOCERA AVX Molded TAJ Cap 6.8µF 20V ±10%","metaDescription":"TAJA685K020TNJ from KYOCERA AVX: 6.8 µF, 20 V, ±10% molded tantalum capacitor in 1206 package.
