Bulk decoupling on a 25 V rail — what the ratings mean
The TPSE336K025R0200: That 200 mOhm ESR is the number that governs ripple handling: at 100 kHz, a 200 mOhm ESR means the cap dissipates about 0.4 W under 1 A ripple, which the molded case can manage without derating at 85 °C. The -55 to +125 °C operating range covers both the industrial floor and the under-hood temperature band. AEC-Q qualification is not stated on this part, so it is not automotive-grade — treat it as a general-purpose tantalum for commercial or industrial boards where the ambient stays below 85 °C for long-life reliability.
Footprint and board-fit — the 2917 case
The molded case has no exposed cathode tab — the termination is a wraparound solder pad on each end, so the reflow profile follows the standard JEDEC tantalum cap profile (peak 260 °C, 30 s above 217 °C). No moisture sensitivity level is listed; assume MSL 1 for molded tantalum caps unless a bake note is on the reel label. The E size code is the manufacturer's case-length identifier — it matches the 2917 footprint, so any replacement with the same code drops in without a layout change.
