What this tantalum capacitor brings to the 35 V rail
The TAJA474M035RNJ is a 0.47 µF molded tantalum capacitor rated at 35 V, with a ±20% tolerance and a 12 Ohm ESR. It belongs to the KYOCERA AVX TAJ series, a general-purpose line widely used for decoupling and filtering in power distribution networks. The 35 V rating provides a comfortable margin on 24 V or 28 V rails, reducing derating concerns in avionics or industrial power supplies. The 12 Ohm ESR is typical for a small-case tantalum; it limits ripple current handling but is adequate for bypassing at moderate frequencies.
The molded construction and surface-mount 1206 case (3.20 mm x 1.60 mm footprint, 1.80 mm seated height) simplify pick-and-place assembly and reflow soldering. The size code A package is a standard JEDEC footprint, so PCB layout is straightforward.
