The TAJW475M035RNJ: This is a standard-stock line item for ongoing BOMs and new designs alike.
4.7 µF at 35 V — decoupling headroom
Rated 4.7 µF at 35 V, this molded tantalum provides a 2.5× voltage margin on a 12 V rail and nearly 3× on a 5 V rail — the derating rule of thumb (50-60% of rated voltage for tantalum) is comfortably met. The 2.2 Ohm ESR is moderate for this capacitance and voltage class; it limits ripple current to roughly 400 mA RMS at 100 kHz, adequate for local decoupling on a mixed-signal board.
The molded case construction resists moisture ingress better than conformally-coated chips, a practical advantage in unsealed enclosures.
2312 (6032 Metric) footprint — W case code
The 6.00 mm x 3.20 mm footprint with a seated height of 1.50 mm matches the standard W case size in the TAJ series. The low profile suits dense PCB stacking or mezzanine card spacing where clearance above the board is tight.
