2.2 µF at 35 V — bulk decoupling for a 24 V rail
The TPSB225M035R2000: Rated 35 V with 2.2 µF capacitance and 2 Ω ESR, this TPS series molded tantalum is sized for bulk decoupling on a 24 V bus — the voltage rating clears the rail with margin, and the ESR sets the ripple current the capacitor can absorb without self-heating beyond the datasheet limit.
-55 to +125 °C — military-temperature range
Active lifecycle — no end-of-life watch
The BOM line is stable for current production; no urgency to stockpile or qualify an alternative.
