The TAJC476K010RNJ: At 47 µF and 10 V, this tantalum holds enough charge to smooth the ripple from a switching regulator feeding a 3.3 V or 5 V digital rail. The 1.2 Ohm ESR limits the ripple current to about 1.5 A RMS at 100 kHz — enough for a 3 A load transient without the cap self-heating past its rating. The ±10% tolerance means the actual capacitance at 25 °C is between 42.3 µF and 51.7 µF — the low end still meets the decoupling target for a typical MCU or FPGA core rail.
At 125 °C the voltage derating curve for tantalum typically drops the working voltage to 2/3 of rated — so at 125 °C ambient, treat the 10 V rating as 6.7 V maximum continuous.
Footprint and board fit
The 2312 (6032 Metric) case measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm. This is the standard size C tantalum footprint — it lands on the same pads as AVX TPS series size C and Kemet T491 size C, so a single PCB land pattern covers multiple sourcing options. The cut-tape (CT) option is available for prototype quantities.
