For a 25 V rail with 100 mA ripple, the self-heating stays under 30 mW, but a higher-ripple supply (e.g., a buck converter output) needs a parallel low-ESR ceramic to share the AC current. The molded construction provides mechanical stability across the range. 1411 (3528 Metric) case, size code B, measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. Surface-mount — the standard 1210 footprint fits the 3528 land pattern without adjustment.","metaTitle":"TAJB685K025RNJ KYOCERA AVX Molded Tantalum Capacitor 6.8 µF","metaDescription":"TAJB685K025RNJ from KYOCERA AVX: Molded tantalum capacitor, 6.8 µF, 25 V, ±10%, 2.8 Ohm ESR, -55°C to 125°C, 1411 (3528 Metric) package.
