What the 110 mOhm ESR buys you on the rail
The TPSC476K016R0110: The 110 mOhm ESR is the spec that matters for ripple and self-heating. The ESR also sets the self-heating limit: at 500 mA RMS ripple, the internal temperature rise from ESR losses is roughly 27 °C above ambient, which you must budget against the 125 °C ceiling. The C size code means the case height is 2.8 mm seated — it fits under a low-profile heatsink or a mezzanine card.
KYOCERA AVX continues to run this TPS series in the C case.
The full military temperature span qualifies this capacitor for avionics, satellite, downhole instrumentation, and engine-bay electronics. The molded construction resists moisture better than a conformal-coated chip — relevant for conformal-coat-over-capacitor decisions in humid environments.
