The TPSE336M035R0100: The 35 V rating gives comfortable headroom on a 24 V supply bus and handles 12 V rails with margin for transients. It belongs to the TPS series, KYOCERA AVX's general-purpose low-ESR tantalum line, and carries the E case code.
The 100 mΩ ESR is the equivalent series resistance at 100 kHz — this is the figure that governs ripple current handling and self-heating. For a switching regulator output, a 33 µF cap with 100 mΩ ESR handles ripple current in the 1–2 A range before internal temperature rise becomes a concern. Operating temperature spans -55°C to 125°C, which qualifies it for industrial enclosures, engine-bay electronics, and outdoor telecom gear. The capacitance stays within tolerance across that band, though ESR roughly doubles at -55°C and drops at high temperature.
