4.7 µF at 16 V — bulk decoupling for a 16 V rail
The TPSB475M016R1500 is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated at 4.7 µF with a 16 V working voltage and ±20% tolerance. The 1.5 Ohm ESR at 100 kHz sets the ripple-current capability and self-heating limit — for a 16 V rail carrying 100 kHz switching ripple, the ESR determines how much AC current the cap can sink before internal temperature rise exceeds the derating curve.
There is no forced redesign window; the BOM line can be replenished against an RFQ without a last-time-buy deadline.
