The 25 V rating gives headroom above a 12 V rail, making it a common choice for bulk decoupling on 3.3 V or 5 V supplies where the input sees a 12 V bus. The 2.8 Ohm ESR at 100 kHz sets the ripple current ceiling — at 6.8 µF and 25 V, this is typical for a B-case tantalum and limits self-heating in high-frequency switching applications. ## Active production — no LTB deadline to chase ## B-case footprint — 1411 / 1210, same body The package is 1411 (3528 Metric) / 1210, size code B, measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 1210 inch-code alias matches the common B-case footprint — confirm the pad layout against the 3528 metric dimensions to avoid a land-pattern mismatch. It fits avionics, downhole tools, and satellite power rails without a grade upgrade — the 25 V derating at 125°C should be checked against the application voltage.","metaTitle":"TAJB685M025RNJ KYOCERA AVX 6.8 µF 25 V Tantalum Capacitor","metaDescription":"TAJB685M025RNJ from KYOCERA AVX: 6.8 µF ±20%, 25 V, Molded tantalum, B-case 1411/1210, -55°C to 125°C, 2.8 Ohm ESR.
