D-case tantalum — footprint and integration story
The TPSD337K004R0100: This footprint matches the industry-standard D-size tantalum land pattern, so the PCB layout is interchangeable with any other D-case tantalum from the same voltage and capacitance class. The 100 mOhm ESR limits ripple current heating; at 100 kHz the self-heating from ripple should be checked against the 125 °C ceiling.
Lifecycle and procurement posture
Listed as Active by KYOCERA AVX, so no last-time-buy clock is running. Date-code consistency and lot traceability are confirmed at the point of shipment; the laser-etched marking on the D case is straightforward to verify against the manufacturer's font and format.
