Keep the RMS ripple current below 100 mA to stay within a 10°C temperature rise above ambient. It is suited for avionics, downhole drilling instrumentation, satellite power buses, and outdoor telecom equipment that sees -40°C cold starts and +105°C enclosures. The molded construction provides mechanical robustness and moisture resistance compared to uncoated chips, which matters for conformal-coated boards in humid or condensing environments. ## Package and footprint — 1411 (3528 Metric) size code B Housed in the standard 1411 (3528 Metric) case with size code B, the body measures 3.50 mm × 2.80 mm with a seated height of 2.10 mm max. Reflow profile follows standard J-STD-020 for a 260°C peak — the molded epoxy body handles the thermal shock without cracking, unlike some conformal-coated parts that can delaminate.","metaTitle":"TAJB105M050RNJ KYOCERA AVX Molded Tantalum Capacitor 1 µF","metaDescription":"TAJB105M050RNJ KYOCERA AVX TAJ series molded tantalum capacitor, 1 µF, 50 V, ±20%, 7 Ohm ESR, -55°C to 125°C.
