The operating temperature from -55 to 125 °C covers military and industrial environments — avionics, downhole instrumentation, and outdoor telecom gear that sees -40 °C startup and 105 °C soak all use this grade. For a 100 kHz buck converter output, the ripple voltage across this cap is ESR × ripple current; a lower ESR part would run cooler but cost more per farad. Case size C (2312 metric, 6.00 × 3.20 mm footprint, 2.80 mm seated height) is a common mid-range body for 47 µF at 10 V — fits the same land pattern as other size-C tantalums from Kemet and Vishay, so a second-source qualification is straightforward.
The part is in regular production and can be ordered against a BOM without a last-time-buy window. The TAJ series is a broad molded-tantalum family; if this specific capacitance/voltage/ESR combination becomes constrained, a functionally equivalent size-C tantalum from a qualified alternate source can be substituted after verifying the ESR and ripple current match the design margin.
Sourcing against the BOM line
The molded case is standard for automated pick-and-place; no special handling beyond MSL 1 (typical for tantalums) is needed.
