At 125°C the leakage current rises per the datasheet curve; derate the applied voltage to 50% of rated for continuous operation above 85°C. The molded 1411 (3528 Metric) case with B case code is a common footprint shared across the TAJ series. ## Molded tantalum — construction and fit Molded construction with a solid manganese dioxide cathode — the same construction as the standard TAJ series. The ±10% tolerance covers the full temperature range; no voltage derating is required at room temperature, but for 125°C operation a 50% derating is recommended per industry practice. Surface-mount 1411 (3528 Metric) package, 3.50 mm × 2.80 mm footprint, 2.10 mm seated height. The B case code matches the standard EIA 3528-21 outline.","metaTitle":"TAJB686K006H KYOCERA AVX Molded Tantalum Capacitor 68 µF","metaDescription":"TAJB686K006H active molded tantalum capacitor, 68 µF, 6.3 V, ±10%, 900 mOhm ESR, -55°C to 125°C, 1411 case.
