The B case (1411 / 3528 Metric) footprint is 3.50 mm x 2.80 mm with a seated height of 2.10 mm. Surface-mount termination suits standard reflow profiles. The 125°C ceiling includes self-heating from ripple current — the 4.5 Ohm ESR means the I²R loss adds to the ambient, so the actual ripple current must be budgeted against the thermal derating curve.","metaTitle":"TAJB225K050RNJ KYOCERA AVX Molded Tantalum Capacitor 2.2 µF","metaDescription":"TAJB225K050RNJ active production molded tantalum cap, 2.2 µF, 50 V, ±10%, -55°C to 125°C, B case.
