The TAJB335K035RNJ: Rated 3.3 µF at 35 V with ±10% tolerance — the 35 V rating gives 2× derating margin on a 12 V rail, which keeps the DC bias capacitance stable and reduces the risk of surge failure in a power-supply output filter. ESR is 3.5 Ohm — for a 3.3 µF part this is typical of a standard tantalum; the ESR limits the ripple current the capacitor can handle without self-heating, so in a high-ripple switching regulator output the part may run warm and should be checked against the ripple current derating curve.
Package and footprint – board-layout fit
Supplied in the 1411 (3528 Metric) / 1210 case size, size code B. The 3.50 mm x 2.80 mm body with 2.10 mm seated height fits a standard 1210 pad layout; the molded case gives consistent dimensions for pick-and-place.
