47 µF, 16 V, 100 mOhm ESR — the TPS series workhorse
The TPSD476K016T0100V: Its 100 mOhm equivalent series resistance (ESR) at 100 kHz is the figure that governs ripple handling — lower ESR means less self-heating in a switching regulator output filter, so this cap runs cooler than a higher-ESR alternative in the same position. Rated for 2000 hours at 125°C, the lifetime test condition matches the full operating temperature ceiling — a 105°C environment roughly doubles the rated life per the Arrhenius model typical for tantalum dielectrics.
AEC-Q200 — the automotive-grade gate
AEC-Q200 qualification means this part passed the stress tests required for automotive passive components: thermal shock, moisture resistance, mechanical shock, and vibration. It is not just a commercial-grade cap with an extended temp range — the qualification adds a reliability screening layer. The operating temperature span of -55°C to 125°C covers the full automotive under-hood and cabin ambient range, with margin on both ends for self-heating.
