That means it has passed temperature cycling, moisture resistance, and mechanical shock sequences that standard tantalums skip. For an under-hood ECU or a chassis-domain sensor module, this rating is the gate the component engineer checks first. ## Capacitance, voltage, and tolerance — the BOM check 4.7 µF at 35 V with ±20% tolerance — the capacitance is nominal at 25°C and 0 VDC bias. Tantalum capacitors lose capacitance under DC bias less than MLCCs do, but the ±20% tolerance band means the minimum capacitance at the operating voltage could be 3.76 µF. If your circuit needs a guaranteed minimum of 4 µF at 35 V, this part is marginal; a higher voltage rating or tighter tolerance code would be safer. The 1411 (3528 Metric) case, size code B, measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. That footprint matches the standard 3528-21 tantalum land pattern — no board respin needed if you are replacing a different manufacturer's B case. ## ESR and ripple current — what 3.1 Ohm at 100 kHz drives The ESR is 3.1 Ohm at 100 kHz — that is the resistive loss inside the capacitor. For a typical DC-DC converter output filter, the ripple current heats the part; at 100 kHz the self-heating from 100 mA ripple is about 31 mW, which is negligible in free air. But if the ripple current is 500 mA, the internal temperature rise approaches 10°C above ambient, which eats into the 125°C lifetime margin. The datasheet's ripple-current derating curve (page 7) is the right reference for your actual load. For volume pricing and current lead time, submit an RFQ with your target quantity and required delivery window.","metaTitle":"TAJB475M035TNJ KYOCERA AVX 4.7 µF 35 V Molded Tantalum","metaDescription":"TAJB475M035TNJ — KYOCERA AVX TAJ series, 4.7 µF ±20%, 35 V, AEC-Q200 automotive, 2000 hrs @ 125°C, 1411 case.
