For a decoupling cap on a digital rail, that ESR adds to the power-supply impedance; for an output filter cap, it limits the ripple current you can pass before the part cooks. The ESR climbs at cold temps, so at -55°C the effective filtering drops; budget for that if the circuit must hold regulation at low temperature. ## Package and footprint — what fits the board The footprint is 3.50 mm x 2.80 mm with a seated height of 1.20 mm — low-profile enough for tight stacked boards, but the molded body means no conformal coating issues on the side fill. You can design it in without worrying about a last-time-buy window closing.","metaTitle":"TAJT685K006RNJ KYOCERA AVX TAJ 6.8 µF Molded Tantalum","metaDescription":"6.8 µF, 6.3 V, ±10% tolerance, 5 Ohm ESR, -55°C to 125°C, 1411 (3528 Metric) package.

A 6.8 µF MLCC in 1206 at 6.3 V might give only 3-4 µF at 5 V bias. Tantalum holds its full value across the voltage range, which matters for timing circuits or filter poles that need stable capacitance."},{"question":"Is TAJT685K006RNJ RoHS compliant?","answer":"The evidence does not explicitly list RoHS compliance status.
