10 µF at 50 V, 500 mOhm ESR — bulk decoupling fit
The TPSE106M050R0500: That ESR figure is the one that governs ripple handling in a DC-DC converter output — at 500 mOhm it can absorb the AC ripple current without excessive self-heating, which is the failure mode that sends tantalums into thermal runaway. The 50 V rating gives a solid derating margin for a 24 V or 28 V rail — standard practice is to stay below 80% of rated voltage for tantalum reliability, so this cap comfortably covers a 40 V bus.
Temperature range and case — -55 to 125°C, 2917 footprint
Operating from -55°C to 125°C, this covers the full industrial and military temperature band — no derating needed for an outdoor telecom base station or an engine-bay ECU that sees 105°C ambient. That footprint is standard across the TPS series — a board layout for a 10 µF 35 V part in the same case accepts this 50 V variant without a pad change. Tolerance is ±20%, which is typical for molded tantalum chips — fine for bulk decoupling and hold-up capacitance where the exact value is less critical than the minimum at the worst-case temperature.
