47 µF at 20 V — bulk decoupling for a 20 V rail
The TPSD476K020R0200 is a 47 µF tantalum capacitor rated at 20 V with a 200 mOhm ESR. That ESR figure is the one that matters for ripple handling: at 100 kHz, a 200 mOhm ESR means the cap dissipates about 0.2 W per amp of ripple current, so the self-heating stays manageable in a typical DC-DC output filter. It is a molded case in the 2917 (7343 Metric) footprint, size code D, standing 3.10 mm max seated height. The molded construction gives it a consistent outline for pick-and-place, and the 2917 pad geometry is standard enough that a layout swap to a different tantalum or polymer cap with the same footprint is straightforward.
Active production — no EOL clock ticking
The TPSD476K020R0200 is listed as Active by KYOCERA AVX. No NRND flag, no last-time-buy notice. The -55°C to 125°C operating range covers the full industrial temperature envelope and the outer edge of automotive ambient. If the board sees sustained 125°C, the voltage derating guideline for tantalum caps is typically 50% — so at 20 V rated, keep the applied voltage under 10 V at that temperature to stay inside the safe operating area.
The TPS series carries general-purpose features. Compliance documentation (RoHS, REACH) is typically provided by KYOCERA AVX at the datasheet or lot level; confirm the specific compliance certificate needed for your receiving inspection at the time of order.
