Temperature range and ESR — the thermal budget
The TPSE476M025R0125: The 125 mOhm ESR is specified at 25°C and 100 kHz — at elevated temperatures the ESR rises, so derate ripple current above 85°C per the manufacturer's curve. The molded construction provides mechanical stability during reflow soldering and resists cracking from board flex, which is a common failure mode in larger case-size tantalums.
