The ±20% tolerance is standard for tantalum — the actual capacitance at 4 V bias will sit near the nominal, but derate the voltage by 20% in design for reliability (3.2 V working max in practice). ## B case, surface-mount — fits the 1210 footprint Manufacturer size code B, which maps to the 1411 (3528 Metric) or 1210 case — 3.50 mm x 2.80 mm footprint, 2.10 mm seated height. Surface-mount, supplied on tape and reel — the reflow profile follows standard tantalum recommendations; no special bake unless the moisture sensitivity label says otherwise.","metaTitle":"TAJB157M004RNJ 150 µF 4 V Tantalum Cap KYOCERA AVX","metaDescription":"TAJB157M004RNJ: 150 µF, 4 V, ±20%, 1.5 Ohm ESR, -55 to 125 °C, Molded, TAJ series.
