47 µF, 16 V, 150 mOhm — the bulk-capacitance decision
The TPSD476K016S0150: The 150 mOhm ESR at 100 kHz is the figure that governs ripple current capability and transient response — lower ESR means less self-heating and better decoupling on a power rail. The -55°C to 125°C operating range covers the full industrial temperature envelope and extends into under-hood automotive ambient conditions, though this part carries no explicit AEC-Q200 automotive qualification in the record.
Active lifecycle — no end-of-life risk on this BOM line
For a BOM cost engineer, the active status and single-source (KYOCERA AVX) supply chain means the part is low-risk for allocation but not dual-sourceable from a second manufacturer without requalification. The molded tantalum construction and D-case footprint are industry-standard, so functional equivalents from other vendors exist but are not pin-compatible drop-ins without PCB layout changes.
