In a 16 V rail with 100 mA ripple, the internal temperature rise is roughly 25 mW × thermal resistance — enough to matter in a confined enclosure. For output filtering on a switching regulator, the 2.5 Ohm ESR sets the output ripple voltage at 250 mV per 100 mA of ripple current, which may require a second capacitor in parallel to meet tight ripple specs. ## Package and footprint — 1411 (3528 Metric) size code B The capacitor is supplied in a 1411 (3528 Metric) surface-mount package, size code B, measuring 3.50 mm × 2.80 mm with a seated height of 2.10 mm. The 2.10 mm height is a constraint for low-profile assemblies — confirm clearance above the tallest component on the same side of the board.","metaTitle":"TAJB685K016Y KYOCERA AVX Molded Tantalum Capacitor 6.8 µF","metaDescription":"TAJB685K016Y molded tantalum capacitor, 6.8 µF ±10%, 16 V, -55°C to 125°C, 2.5 Ohm ESR.
