Bulk capacitance for a 6.3 V rail
The TAJW476M006RNJ is a 47 µF molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 6.3 V with ±20% tolerance. The 47 µF value suits it for bulk decoupling on low-voltage digital rails, where it absorbs transient current demands and stabilises the supply. For a 47 µF part, this ESR is typical for a standard MnO₂ tantalum — expect higher ripple heating than a low-ESR polymer capacitor, so derate the ripple current per the datasheet temperature curve.
The molded case provides mechanical protection and moisture resistance compared to conformal-coated chips.
The footprint is 6.00 mm × 3.20 mm with a seated height of 1.50 mm. This is a standard tantalum chip size — the land pattern matches the EIA-535BAAC specification. The low profile (1.50 mm) allows use in compact PCB stacks where height is constrained.
