Parametric fit — 470 µF, 10 V, 40 mOhm ESR
The TPSV477K010R0040: The 40 mOhm ESR is the figure that governs ripple current handling and transient response in a power rail — a lower ESR means less self-heating and better filtering of high-frequency ripple. Tolerance is ±10%, which is the standard grade for bulk decoupling and output filtering where the exact capacitance is not the critical parameter.
Temperature range and deployment context
Rated for -55°C to +125°C, this capacitor spans the full industrial temperature envelope and reaches into the automotive under-hood band. At 125°C the leakage current and ESR derating curves from the TPS series datasheet apply — the 40 mOhm ESR figure is typically specified at 25°C and rises with temperature. The surface-mount 2924 package is a common footprint for high-capacitance tantalum parts in power supply outputs, DC-DC converter bulk caps, and hold-up storage on processor rails. The molded construction provides mechanical stability during reflow and resists cracking from board flex better than conformally-coated parts.
